middle of the 2000s, the scale and persistence of hedge
funds’ success was transforming the structure of the industry.
The first generation of hedge-fund titans had been seen as freakish geniuses, whose eye-popping returns were possibly lucky and certainly
not reproducible. But by 2005 nobody could argue that hedge funds
were exceptional in any way: More than eight thousand had sprouted,
and the long track records of the established funds made it hard to dismiss their enviable returns as the products of good fortune. Bit by bit, the
old talk of luck and genius faded and the new lingo took its place—at
hedge-fund conferences from Phoenix to Monaco, a host of consultants
and gurus held forth about the scientific product they called alpha. The
great thing about alpha was that it could be explained: Strategies such as
Tom Steyer’s merger arbitrage or D. E. Shaw’s statistical arbitrage delivered uncorrelated, market-beating profits in a way that could be understood, replicated, and manufactured by professionals. And so the era of
the manufacturer arrived. Innovation and inspiration gave way to a new
sort of alpha factory.
You could see this transformation all over the hedge-fund industry. By
the early 2000s, there was no longer much doubt that long/short equity
stock picking, as practiced by Julian Robertson’s Tiger, could deliver
308 MORE MONEY THAN GOD
market-beating returns. The challenge was not so much to invent the
strategy; it was to implement it successfully. Dozens of Tiger look-alikes
sprang up to do the job, many of them run by men who had themselves
worked for Tiger; and an eager industry of hedge-fund consultants and
funds of funds emerged to allocate capital to the most promising among
them. The biggest sponsor of Robertson clones was none other than Robertson himself. After shuttering Tiger in 2000, he turned his offi ces into
an incubator for “Tiger seeds,” which managed his money, benefi ted from
his coaching, and used the prestige of association with the great man to
raise more capital from outsiders. Under the old Tiger model, Robertson
had maintained personal control of all the big investment calls, but now
he let his protégés run their own shows: He had switched from inventing
an investment technique to franchising it. The switch provided Robertson
with a lucrative final chapter to his illustrious career. By 2006 the reinvented Tiger complex was managing $16 billion. The premises on Park
Avenue grew bigger than ever.
The purest expression of the new factory chic was the so-called multistrategy hedge fund. Rather than claiming an edge in a particular investment style, the multistrategy funds began from the principle that you
could develop an edge in whatever style you liked: You just had to hire
the people. Like a pharmaceutical giant that vacuums up ideas from university researchers and biotech start-ups, the multistrategy factories collected multiple alpha-generating strategies under one roof, blending them
together so as to diversify away risk, then shifting capital among the various styles according to market conditions. The factories talked little about
invention and a lot about process; they viewed hedge funds less as vehicles for financial creativity than as financial products. A Chicago-based
hedge fund called Citadel emerged as a prime exponent of the multistrategy mind-set; its goal, an executive explained, was “to see if we can turn
the investment process into widget making.”1
Ken Griffi n, Citadel’s thirtysomething boss, was a keen consumer of management texts. His staff
sneaked glances at the tomes on his desk so that they could brace themselves for the next six-step plan, and he pushed people out of his company
PREMONITIONS OF A CRISIS 309
with a mechanical determination. Griffin liked to compare hedge funds
to buses. People get on. People get off. The bus keeps rolling forward.
The new multistrategy funds grew from babies to behemoths in the
blink of an eye. Again, Citadel was a case in point. Griffin had started
out trading convertible bonds from his dorm room at Harvard, and at
the start of 2000, when he was still just thirty-one, he was running about
$2 billion. Then the age of the manufacturer arrived and Citadel took off,
so that its assets swelled to $13 billion by 2007. The firm found it could
charge clients almost anything it pleased: It billed them for expenses
amounting to more than 5 percent of their capital before slapping on the
20 percent performance fee.2
Griffin’s personal earnings were said to be
the second-highest in the industry, just behind James Simons, and he let it
be known that Citadel would one day compete with Goldman Sachs and
Morgan Stanley.3
Meanwhile, Eton Park Capital Management, launched
in 2004 by an ex-Goldman merger arbitrageur named Eric Mindich,
offered another example of multistrategy growth. Mindich raised $3 billion in assets before even opening his doors; four years on, he was managing $11 billion. During the 1990s, all the top hedge funds had struggled
with the burden of bigness, and many had returned capital to investors.
But by 2007 alpha factories managing $5 billion plus accounted for 60
percent of the assets in the industry.4
A magazine published a list of all the
hedge funds in the “Billion-Dollar Club.” If you were not on the list you
were a nobody.
There was a powerful logic in this rush to bigness. Small companies
may excel at generating ideas, but big companies excel at implementation. Once the hedge-fund industry had progressed through its garageworkshop phase, it took sleek professional outfits to bring its inventions
to market. The successful alpha factories boasted state-of-the-art computers that executed lightning trades, legal departments that understood the
rules in multiple countries, treasury departments that negotiated the best
terms from brokers, and marketing departments that churned out glossy
monthly reports to satisfy high-maintenance institutional investors. Since
their edge lay in the efficiency of their platforms rather than the originality
310 MORE MONEY THAN GOD
of their ideas, it was natural to use the platforms to support multiple
alpha-generating strategies—and multiple strategies meant that the new
funds could manage huge amounts of money. The multistrategy format
responded to customer pressure too. The fund-of-funds industry, which
collected money from endowments and pension funds and allocated it to
hedge funds, had amassed almost $400 billion in assets by 2005, partly
by promising to shift capital nimbly among different hedge-fund strategies as market conditions altered. The way MBA-minded hedge funds saw
it, they could cut out the middleman. If endowments were looking for a
product that would shift flexibly among strategies, multistrategy hedge
funds would build the widget that the clients wanted.
And yet, for all its logic, the sudden growth of alpha factories made wise
observers feel uneasy. Too many people were making too much money too
fast. Opportunistic consultants staged workshops on how to open a hedge
fund; a book called Hedge Funds for Dummies appeared in the stores; and
grandees with no known background in asset management, such as Madeleine Albright, the former secretary of state, jumped into the industry.
The frenzy recalled the extremes of the leveraged-buyout boom in the
1980s or the dot-com mania in the 1990s. Surely this bubble could not
last? Wasn’t it bound to end painfully?
IN THE MID-2000S, AS THE HEDGE-FUND BU BBLE WAS
growing, an outfit named Amaranth emerged as the very model of the
modern alpha factory. Its founder, Nick Maounis, was a convertiblearbitrage specialist by background, but he had hired experts in merger
arbitrage, long/short equity investing, credit arbitrage, and statistical arbitrage; and in 2002, following the collapse of the corrupt energy company
Enron, Maounis had snapped up several stranded employees to open an
energy-trading operation. Maounis made the standard arguments for this
mission creep: A blend of alpha-generating strategies would diversify away
risk, and Amaranth would move capital aggressively among strategies as
market conditions shifted. The fund’s energetic shape-shifting was a point
of pride. In the first months after Amaranth’s launch in September 2000,
PREMONITIONS OF A CRISIS 311
nearly half of its capital had been focused on merger arbitrage. A year
later, that strategy had been cut to practically zero, and more than half
of Amaranth’s capital was focused on convertible arbitrage. Scroll forward another year, and the portfolio began to shift into bond trades, and
then into statistical arbitrage and energy. There seemed no good reason
for a pension plan to hire a fund of funds when it could go directly to
Amaranth, bypassing the middleman’s fees, particularly since Amaranth’s
results were excellent. In its first three full years of operation, Amaranth
returned 22 percent, 11 percent, and 17 percent—this at a time when the
S&P 500 was mostly heading downward.
Yet for all Amaranth’s glittering appearance, there was a certain hollowness about it. Contrary to his marketing patter, Maounis had no clear
edge in deciding which strategy to shift into. He upped his allocation to
investment styles that had worked well recently and cut back on those that
fared poorly; but there was no sure way to identify which strategies would
succeed in the near future.5
Moreover, precisely because alpha had become
a commodity, dozens of rival factories were driving down returns by manufacturing the same thing: Amaranth’s shape-shifting was less about cleverly timing market cycles than about desperately searching for the next
trick to keep profits from tanking.6
And because Maounis was allocating
capital to specialist traders whose books were difficult to understand, his
decisions were necessarily affected by instinct. Gut feelings about the various traders on his team could sway decisions dangerously.
These dangers came together in the shape of a young Canadian named
Brian Hunter. Standing six feet five inches tall, occasionally donning a
jersey of the National Hockey League’s Calgary Flames, and equipped
with a graduate degree in math, Hunter was imposing physically as well
as intellectually. He was earnest, soft-spoken, and unfailingly calm, and
from the moment he landed at Amaranth in 2004, his returns from trading natural gas stood out conspicuously.7
He had spotted an anomaly in
winter gas prices. Unlike oil, which is shipped around in tankers, natural
gas is delivered mainly in pipelines; supply routes cannot easily be changed
to fill unexpected local shortages. As a result, gas prices are volatile: Time
and again, a blast of cold weather would cause demand for household
312 MORE MONEY THAN GOD
heating to spike, and in the face of rigid supply, prices would leap upward.
Hunter’s discovery was that options whose value would shoot up in a
shortage were strangely cheap—they represented bargain weather insurance. Hunter loaded up on these options, figuring he had found a classic
asymmetrical trade: The most he could lose was the small cost of buying
the options, but if a shock hit the market and the gas price spiked, he
could earn many times more than that. Another way of cashing in on the
same insight was to buy a pair of futures contracts: Hunter would go short
a summer contract and long a winter contract, betting that the narrow
spread between the two would widen if winter prices leaped upward. The
strategy had worked in recent winters, and in November 2004 it came
good again. The price of natural gas jumped to around 80 percent above
its low point in the summer, and Amaranth cashed in handsomely.
In the spring of 2005, Maounis confronted an unpleasant dilemma.
Many of Amaranth’s strategies were faring poorly. Convertible arbitrage
had hit a wall and showed no sign of recovering. Maounis had invested
heavily in statistical arbitrage, telling colleagues he wanted a piece of James
Simons’s action, but he had little to show for it. The one star act in the
Amaranth lineup was Brian Hunter and his winter gas; but in April, Maounis learned that Hunter had been offered a $1 million bonus to sign on
with a rival firm, SAC Capital. Feeling his back against the wall, Maounis
took a chance. Rather than lose his star player, he promoted him. Hunter
became cohead of Amaranth’s energy desk, gaining the authority to place
his own trades; meanwhile, Maounis pumped up the share of his firm’s
capital allocated to the energy desk from 2 percent the previous spring
to around 30 percent. With these two decisions, Maounis effectively bet
his company on a thirty-two-year-old trader who had been with him for
barely one year. In the go-go atmosphere of the mid-2000s, this was the
sort of thing that happened.
Hunter’s promotion was all the more remarkable given his background.
He had come to Amaranth from Deutsche Bank, where he had supervised
gas trading. In December 2003, his trading group had lost $51 million
in a single week, but Hunter’s response was nothing if not brazen. In a
suit he later brought in New York state court, Hunter ascribed the loss
PREMONITIONS OF A CRISIS 313
to “an unprecedented and unforeseeable run-up in gas prices,” as though
his failure to foresee the market’s behavior rendered him blameless. He
pointed to the “well-documented and widely known problems” with
Deutsche Bank’s trading and risk-management software, which made it
hard to exit losing trades—as though his taking of excessive risks could
be laid at the door of Deutsche’s managers. Hunter also argued that even
though his group had registered a loss, he himself had earned $40 million
for the bank during 2003: Therefore, he deserved a bonus. By February
2004, Deutsche Bank’s managers had concluded that there was no place
for Hunter on their trading team. This was the man whom Amaranth was
now promoting.8
Four months after that promotion, Maounis had cause to celebrate.
Hunter had continued to bet that winter gas prices might spike, and suddenly the mother of all weather shocks arrived: In August Hurricane
Katrina slammed into the Louisiana coastline, flooding New Orleans and
ravaging gas-production rigs in the Gulf of Mexico. The next month Hurricane Rita followed, and the nation’s gas supply was hit again. By the
end of September, natural gas prices had hit a record, and the effect on
Amaranth’s returns was dramatic. Having been down 1 percent in the
first half of 2005 because of the sluggish performance of most of its strategies, Amaranth was up 21 percent by the end of the year, while the average hedge fund mustered a return of just 9 percent. Hunter and his gas
trades earned $1.26 billion, accounting for just about all of Amaranth’s
profits, and Hunter reportedly pocketed a tenth of that.9
Thanks to his
performance, Amaranth’s assets swelled to about $8 billion, making it the
world’s thirty-ninth-largest hedge fund. In its annual Christmas mailing,
Amaranth sent clients toy gasoline pumps and a card that quoted Benjamin Franklin. “Energy and persistence alter all things,” the card proclaimed. Seldom had one of the Founders been taken so out of context.
On any reasonable reckoning, Hurricanes Katrina and Rita constituted
freak events. But whereas Hunter had been ready to blame unforeseeable
extremes for his Deutsche Bank losses, he was happy to take credit when
unforeseeable extremes made him a hero. Maounis grew increasingly
enamored of his young star. He seemed to view Hunter as a convertible
314 MORE MONEY THAN GOD
arbitrage trader transported to a different space. He was generating profits while taking little risk: There was no way that winter gas would fall
below the price of summer gas, so his potential losses appeared limited.10
Amaranth’s risk department only reinforced Maounis’s conviction; at one
point, a member of the risk team responsible for natural gas assured Maounis that Hunter was the greatest commodity trader he had ever witnessed.
Hunter had no difficulty persuading Maounis to allow him to move his
family and trading team to his native Calgary. He commuted to his Canadian office in a Ferrari, though sometimes snowy conditions forced him
to use a Bentley.
During the first months of 2006, Hunter’s successful run continued.
His trades earned profits of roughly $2 billion between January and the
end of April, again driving nearly all of Amaranth’s performance. At a time
when the average multistrategy hedge fund was up just 5 percent since the
year’s start, Amaranth was up roughly six times more; Maounis began to
say that, although he had failed to strike gold in statistical arbitrage, he
had discovered another secret weapon that was just as potent.11 And yet to
some savvy observers, Hunter’s extraordinary profits were cause for alarm.
There was no way that Hunter could be generating this sort of money
without taking outlandish risks; and besides, there was a darker worry.
With the rise of the new alpha factories, hedge-fund capital devoted to
energy trading had soared from around $5 billion in 2001 to more than
$100 billion in 2006: The trades were growing crowded. Thanks to this
flood of capital, any strategy that made sense to energy specialists at hedge
funds was almost bound to come good as others piled in. But it could also
blow up if the stampede reversed itself.
In the case of Brian Hunter, an extreme version of this phenomenon
seemed to be occurring. The weight of his own money might be driving
his profits. Amaranth had allowed him to ramp up his positions in a niche
market: By the end of February, Hunter held an astonishing 70 percent
of the natural-gas futures contracts for November 2006 delivery on the
New York Mercantile Exchange and about 60 percent of the contracts
for January 2007. By means of this enormous position, Hunter was betting that November gas would fall in value and that January would rise;
PREMONITIONS OF A CRISIS 315
and so long as he added aggressively to his wager, his view was likely to
be self-fulfilling. After all, it was not clear that his strategy was making
money because market fundamentals were on his side. By early 2006,
gas output had recovered from the devastation of the hurricanes, and
mild winter weather was reducing gas demand, so that by April the quantity of gas held in storage was nearly 40 percent above the previous fiveyear average. Under these circumstances, the success of Hunter’s bet on
summer/winter spreads seemed hard to explain—except when you looked
at the astonishing growth in his positions. By around the end of April,
Amaranth owned upward of one hundred thousand NYMEX contracts,
or more than 40 percent of the total outstanding for all months on
the exchange. Hunter was a momentum trader who traded on his own
momentum.12
In May 2006, a team from the private-equity giant Blackstone visited
Hunter in Calgary. Blackstone ran one of the longest-standing funds of
funds, and it had invested $125 million in Amaranth. But now it was
having second thoughts. Amaranth might be up a whacking 13 percent
in April alone, but the size of Hunter’s profi ts showed he was taking dangerously large bets in a volatile market. Amaranth’s risk control department had calculated that because winter gas prices would never fall below
summer prices, the most Hunter could lose in a single month was $300
million, a tolerable 3 percent or so of equity. But Hunter’s own trading
had rendered this assessment obsolete: The spread between summer and
winter gas had widened from $1.40 in mid-February to $2.20 in late April
as Hunter had built his positions, meaning that there was plenty of room
for the spread to shrink disastrously. Besides, the small size of the gas
market—and the fact that the main buyer of Hunter’s positions was none
other than Hunter himself—created a liquidity risk: Hunter would have
nobody to sell to if he needed to get out of a position. Blackstone informed
Amaranth that it would withdraw its capital at the next opportunity.
There was a penalty fee for short-notice redemptions, but Blackstone was
happy to pay it.13
Meanwhile, Maounis was finally reckoning with the fact that his star
trader had overreached himself. He told Hunter to cut back on his risk,
316 MORE MONEY THAN GOD
but this was easier said than done: Nobody wanted to buy Amaranth’s
contracts, just as the Blackstone team had worried. The moment Hunter
tried to unload some of his positions, the market turned, and the glorious results of April were followed by horrifying losses. By the end of May,
Amaranth was down by more than $1 billion—nearly four times more
than the risk department had deemed possible.
Maounis and his lieutenants scrambled to stabilize their operation.
Traders in other strategies were told to cut back positions in order to free
up capital, and Amaranth paid Morgan Stanley a large fee to shoulder
some of Hunter’s exposure.14 But it was too little, too late. Hunter’s wild
profits and losses had come to the notice of other gas traders, and it was
clear that his positions were too big to hold on to. What’s more, there
was no particular mystery about what these positions were: You just had
to check which pairs of contracts had widened during March and April
to figure out which ones Hunter had been piling into.15 Like Long-Term
Capital caught in its bond trades, or like Julian Robertson caught in US
Airways, Amaranth was trapped. “It was naïve to think that they could
get out of the market with a size of 100,000 positions,” one rival trader
later said. “I knew Amaranth would eventually implode. It was just a
question of when.”16
Amaranth managed to hang on through the summer. Hunter was
under instructions to reduce his positions, but since he could not do
that without incurring crippling losses, he played a waiting game, hoping that something would let him out of his predicament.17 At the end
of July, the rumor of another late-summer hurricane brought the old
bravado back. Hunter jacked up his bets sharply, causing the summer/winter spreads to widen and triggering the implosion of a rival hedge fund
named MotherRock that had the opposite bet on.18 In August, Maounis granted an interview to the Wall Street Journal, bravely declaring,
“What Brian is really, really good at is taking controlled and measured
risk”; looking back on that extraordinary comment, one Amaranth veteran compared Maounis’s enduring faith in the young man to that of a
jilted lover.19 But the moment of truth was approaching. Amaranth suffered losses at the end of August and faced a margin call from its brokers.
PREMONITIONS OF A CRISIS 317
The hurricane season ended uneventfully. Predatory rivals began to target
Amaranth’s positions.20
ON A RAINY MID-SEPTEMBER DAY, MAOUNIS TOOK A LIMousine ride from his office in Greenwich to the Pierre Hotel in Manhattan. The traffic was bad; he should have taken the train; but managers of
multibillion-dollar hedge funds are seldom at home on public transport.
Maounis was on his way to a Goldman Sachs hedge-fund conference that
was emblematic of the times. A ballroom was set up with dozens of tables,
each manned by a team of hedge-fund chieftains; groups of institutional
investors moved from stall to stall, listening to a pitch and then hurrying
off to hear the next one. Maounis speed-dated his way through a couple
of investor groups, repeating the patter that he knew by heart—Amaranth
had a world-class fundamental equity team, a world-class credit team, a
world-class quantitative team, a world-class commodities team, and all of
this was wrapped up in a world-class infrastructure. Then an unwelcome
e-mail arrived. There was trouble back at the offi ce.
That Thursday, September 14, was effectively the end for Amaranth.
The fund lost $560 million in a single day, as the spread on one of its key
summer/winter positions collapsed to a third of its size at the start of September. At a tense meeting at Maounis’s home that evening, Amaranth’s
top brass agreed they needed to raise capital immediately to meet margin
calls. Maounis called Goldman Sachs to see if it would buy his energy
portfolio. Other Amaranth officials reached out to other banks, desperately hoping for a bid from somewhere.
By Saturday morning, squadrons of investment bankers were descending upon the Amaranth office in Greenwich, jamming its parking lot with
fancy cars and devouring the Pop-Tarts in its pantry. Teams of intense
analysts conferred anxiously with bosses at country homes in the Hamptons; meanwhile, Amaranth’s positions hemorrhaged money in after-hours
trading. Goldman made an offer, then Merrill Lynch made an offer, and
early on Monday morning Amaranth thought it had a deal to stabilize the
fi rm by selling a chunk of its assets to Goldman. It looked as though the
318 MORE MONEY THAN GOD
Long-Term Capital plotline would repeat itself. A risk-loving hedge fund
had blown up. The Wall Street establishment would pick up the pieces.
Maounis knew he had to get the news of Goldman’s offer out fast. The
New York Mercantile Exchange would open soon. By now every commodity trader in the world had heard of Amaranth’s distress, and it would
be open season on Hunter’s gas positions. Maounis sent out a letter to his
investors, reporting that Amaranth had lost half the capital it had managed at its peak, but assuring them that a deal to raise fresh capital was
“near completion.”
That Monday morning in Chicago, Ken Griffin, the boss of the multistrategy fund Citadel, was working out at home on an elliptical trainer.
The contraption was rigged up with monitors so he could keep track of
the news at the same time as his e-mail, and a message from Scott Rafferty, Citadel’s head of investor relations, popped up in Griffi n’s in-box.
The e-mail reported that Amaranth was down 50 percent. For a second or
two, the number didn’t fully register; Griffin continued to pump the pedals up and down, thinking, It can’t say that. Then he stopped and hurried
to the phone. He needed to speak to Rafferty.
“Fifty?” Griffin demanded. “Over what period?”
“A month,” Rafferty responded.
Griffin thought about what Vinny Mattone had told Meriwether when
Long-Term Capital was failing. If you are down by half, you are not going
to recover.
Meanwhile in Greenwich, Maounis organized a conference call to
clinch the deal with Goldman. But when the two firms began talking,
along with officials from the NYMEX, Amaranth’s clearing broker, J.P.
Morgan, torpedoed the project. J.P. Morgan’s brokerage department had
lent the firm money to finance its gas trades, holding the futures contracts
as collateral; now that the value of this collateral was doubtful, the bank
was uncertain of repayment. The law gave J.P. Morgan the right to pursue Amaranth’s assets through the bankruptcy courts, and even to claw
back assets from other firms that bought them as Amaranth was going
under. From Goldman’s perspective, the threat of a clawback created an
impossible hurdle: It was hard enough to value Hunter’s gas book amid
PREMONITIONS OF A CRISIS 319
all the market turmoil, but legal uncertainty made the deal unthinkable.
Goldman wanted Morgan to promise not to come after it through the
bankruptcy courts. Morgan balked and the deal faltered.
As Wall Street’s banking titans wrestled one another to a stalemate,
Amaranth’s chief operating officer, Charles Winkler, got a note from his
assistant. He had received a call from Ken Griffin, and he hurried to his
office to return it.
Winkler had worked for Griffin at Citadel, and the two men had been
friends. But when Winkler got Griffin on the line, he found he was not
in the mood for pleasantries. “Charlie, what can we do and how can we
help?” Griffi n demanded.
This was an audacious question. Amaranth’s gas positions had already
bled $4 billion or $5 billion by Monday morning; how could a $13 billion
hedge fund digest this radioactive portfolio? If the likes of Goldman had
worked through the weekend without nailing a deal, what made Griffi n
think he could do better?
Winkler knew Griffin too well to write him off, so he answered his
question forthrightly. “It’s real simple,” he said. “We need a bridge loan
and a couple hundred million to stay in business.”21
Griffin began marshaling the resources of the firm that he had built
around him. Buying a book that constituted a large chunk of the entire gas
market would involve multiple risks: He needed to get his mind around
the logic of the trades, how they were financed, who the counterparties
were, whether Citadel’s computer systems were capable of handling them.
The whole premise of a multistrategy hedge fund—that the edge lay in
the efficiency of the platform—would now be tested to the full. If Griffin
thought his firm was a potential rival to Morgan Stanley and Goldman
Sachs, this was his chance to prove it.
Griffin arranged some forty Citadel staffers into groups to work on
the transaction. He put two lieutenants on a plane to Greenwich, and the
pair of them showed up looking half the age of their investment-banking
rivals. Meanwhile, he got on a conference call with Maounis and his top
advisers. By lunchtime the discussion had gone way beyond a bridge loan;
Amaranth was losing money so fast that it needed to off-load all its energy
320 MORE MONEY THAN GOD
positions, not just its gas positions. The more Amaranth’s positions unraveled, the greater Griffin’s advantage over his investment-banking rivals:
For the banks, every movement of the goalposts required consultation up
and down a chain; Griffin, chief executive and chief deal maker rolled
into one, was free to react instantly. The same speed advantage applied
at lower levels of the firm. Citadel’s technology chief knew how to get
trade data transferred from Amaranth’s computers, loaded into Citadel’s
system, and synced up with Citadel’s accounting and risk-management
software: A larger bureaucracy might have required a committee or two
to do that.22 In the Long-Term Capital crisis eight years earlier, Goldman
Sachs had announced an interest in buying the distressed portfolio but
had not pulled off a deal. This time a hedge fund had grown large enough
to play in the big league, and it was proving relentlessly effective.23
By the evening, the talks between Amaranth and Citadel had eclipsed
the talks with all the various investment-bank suitors. But one obstacle
remained. Amaranth’s sale of its energy book might lead to bankruptcy,
in which case the transaction might be subject to review by a court. Like
Goldman Sachs earlier that day, Citadel could not value Amaranth’s book
in the face of this uncertainty.
Griffin and his team worked through the night, looking for a way
around this legal obstacle. Then, in a lucky break, a solution arrived on
Tuesday morning. An executive from J.P. Morgan called to propose a deal:
Morgan would waive its right to claw back assets in bankruptcy provided
it could be the 50 percent purchaser of Amaranth’s positions. Griffin
accepted, but then a new challenge arose: What if some other creditor
pressed a claim on Amaranth that undermined Citadel’s calculations?
Assessing this risk required understanding the nonenergy parts of Amaranth’s portfolio: Was there another broker that had fi nanced trades that
were now insufficiently backed by collateral? Griffin did not know the
answer, and for a moment the deal seemed set to slip away. But then Bob
Polachek, one of the two Citadel staffers who had camped out in Greenwich, came up with the missing information. He had taken it upon himself
to check all of Amaranth’s brokerage statements by working through the
PREMONITIONS OF A CRISIS 321
previous night. He assured Griffin that there were no undiscovered holes,
and at 5:30 the next morning, the sale of Amaranth went forward.24
The sale was a triumph for Griffin and his investors. Partly thanks
to J.P. Morgan’s offer, but also because Citadel’s execution platform had
proved at least as good as those of the top banks, a hedge fund had stolen
a deal that Wall Street had regarded as its own. The moment Citadel and
J.P. Morgan took ownership of Amaranth’s portfolio, its value started to
come back; predatory traders could see that the gas contracts were no
longer about to be dumped, so they cut their bets and prices recovered.
Citadel eventually earned a profit of about $1 billion from the transaction.
Griffin’s plan to build the next Goldman Sachs had taken a signifi cant step
forward.
AMARANTH’S COLLAPSE CONFIRMED THAT HEDGE FUNDS
had entered bubble territory. They had grown too fast for the available
talent; under pressure to perform, they were capable of granting inexperienced traders the leeway to blow up spectacularly. The multistrategy
format made this danger especially acute. Veterans such as Stan Druckenmiller or Louis Bacon understood risk because they traded every day, and
they were determined to avoid a major loss because their own savings
and reputation were bound up in their companies. But the new alpha
factories were structured in a different way: They believed in delegation.
The boss of a large multistrategy fund could not hope to be an expert
in every risk his traders took, particularly when fast asset accumulation
compelled equally fast adaptation to new styles. And once risk decisions
were delegated down the chain, the multistrategy funds had to contend
with a mild version of the problematic incentives that plague large banks
and brokerages. Traders want bonuses; bonuses are won by betting big;
and a firm’s central risk department seldom controls wizards who acquire
an aura of invincibility. By the time Amaranth folded, $6 billion of its
investors’ equity had gone up in smoke, a larger quantity than Long-Term
Capital had incinerated.
322 MORE MONEY THAN GOD
Yet Amaranth’s collapse could not fully explain the calls for regulation
that followed. Charles Grassley, the chairman of the Senate Finance Committee, complained in a letter to Treasury secretary Henry Paulson that
ordinary Americans were increasingly exposed to hedge funds via their
pension plans; he demanded to know why the funds were allowed to get
away with secrecy. But Amaranth had disclosed its strategies to its investors in monthly reports; indeed, it was the lack of secrecy that had made
it a target once the market turned against it. Likewise, a survey of private
economists conducted by the Wall Street Journal found that a majority
favored tougher oversight for hedge funds, and one popular regulatory
measure was compulsory registration with the Securities and Exchange
Commission. But it was not at all clear what registration would achieve.
As a result of Amaranth’s failure, American taxpayers suffered no harm;
there was no round-the-clock crisis meeting at the New York Fed and
no apparent damage to the fi nancial system. The pension funds that lost
money were angry, but Amaranth had represented a tiny share of their
assets. The effect of the fund’s collapse was no greater than the effect of a
bad day for the S&P 500. In sum, the market had disciplined Amaranth
for its errors while inflicting minimal damage on the wider economy. No
regulatory clamp could have done better.25
Ever since Long-Term Capital’s demise, Wall Street had worried about
the next hedge-fund blowup. Now the event had taken place, and the
scars were barely visible. The critics of hedge funds continued to worry
that these leveraged monsters could ignite systemic fires—after all, LongTerm Capital had done so. But Citadel’s lightning purchase of Amaranth’s
portfolio had proved that there was another side to this story. Perhaps
hedge funds might occasionally ignite fires. But they could also be the
fi refi ghters.

Riding the Storm
Daniel Sadek did not have an easy childhood. Born in Lebanon in
1968, his schooling was interrupted by the country’s civil war,
and his body was scarred by a gunshot wound and a fl ying piece
of metal. He left Lebanon for France, then fetched up in California at
eighteen, landing jobs as a gas-station attendant and then later as a car
salesman. But around 2000, the scales fell from his eyes. He was selling
Mercedes cars—lots of them, one after the next—to customers who were
in the mortgage business. Discovering that he could get a license to sell
home loans without taking classes, Sadek embarked upon a fresh career.
If he had wanted to become a professional barber, he would have needed
1,500 hours of training to qualify for a state license.
By 2005, Sadek’s company, Quick Loan, had seven hundred employees. It was one of the top fifty “subprime” lenders in the nation, meaning
that it specialized in customers who were too risky to qualify for normal
mortgages. Its marketing campaign was not subtle. “No income verifi cation. Instant qualification!!” promised one ad. “You can’t wait. We won’t
let you,” proclaimed the company slogan. The California Department of
Corporations recorded a string of complaints against Quick Loan, including allegations of fraud and underwriting errors.1
But Sadek did not let
that cramp his style. He bought a mansion on the coast and an apartment
324 MORE MONEY THAN GOD
in Vegas; he sported a necklace, flip-flops, and long hair; he acquired a
collection of fast cars, some restaurant investments, and a movie company.
When his actress girlfriend needed a film part, he bankrolled a production called Redline. It was “an action flick loaded with cars, chrome, and
silicone,” the Boston Globe’s reviewer wrote, “everything you’d expect it to
be, and yet so much less.” During the course of filming and promoting the
movie, the cast demolished more than $2 million worth of Sadek’s sports
cars. “Fear nothing; risk everything,” ran the movie’s tagline.
In 2006, Kyle Bass, a hedge-fund manager in Dallas, heard about Sadek
and his filmmaking. The story confirmed what Bass was starting to suspect: The American mortgage market was in the grips of something truly
wild—a bubble that exceeded anything that might exist within the hedgefund industry. Between 2000 and 2005, the volume of risky subprime
loans had quadrupled, and a growing share of these loans was fl owing to
people who could not repay. “Prior bankruptcy. Tax Liens. Foreclosures.
Collections and Credit Problems. OK!” proclaimed another Quick Loan
ad, as though the firm was actively seeking out deadbeats. Sadek’s attitude
toward this seeming suicide was summed up by his movie. As Kyle Bass
put it later, “When they started catapulting Porsche Carrera GTs and he
says, ‘What the hell, what are a couple of cars being thrown around?’ I’m
thinking, ‘That’s the guy you want to bet against.’ ”2
Around the time
that Amaranth was blowing up, Bass and his company, Hayman Capital,
figured out how Sadek’s mortgages were being packaged together and sold
off in the form of mortgage bonds. Bass shorted a large quantity of those
bonds, then settled back and waited.
Other hedge-fund managers had similar epiphanies. For Michael Litt,
the cohead of a large alpha factory called FrontPoint Partners, the light
went on when he visited the mortgage desk at Lehman Brothers. The
mortgage team had recently relocated to a gigantic new trading fl oor; and
while Litt was touring the premises, he heard a group of traders teasing
one of their buddies. A tailor had come to measure the men for some new
$6,000 suits, and this guy had ordered only one—to any self-respecting
mortgage jock, he was positively wussy! A little while later, Litt was on a
plane home from London, reading a report from the Bank for International
RIDING THE STORM 325
Settlements that explained how sophisticated finance had suppressed market volatility. Litt remembers thinking that something was wrong; looking out the window he could see the outline of Greenland, which had
once been hospitable to human settlement and then had frozen over. At
forty thousand feet it suddenly hit him. Volatility was low because the
world was awash with wild money; but abundant liquidity was giving the
false sense that stability was due to some magical structural improvement
in the financial system. Investors from Asia to Arabia were wiring billions
of dollars to fund managers in New York, buying every piece of paper that
Lehman’s mortgage desk could sell, and yet the smart folks at the Bank
for International Settlements appeared to be missing the freeze that would
follow. Litt rebalanced FrontPoint’s portfolio to get ready for a shock. In
the fall of 2006, the firm bet against the subprime mortgage sector and
took a bearish stance in several other trading strategies.3
Over the course of the next year, Hayman Capital and FrontPoint
both profi ted handsomely.4
But the man who made the mother of all
killings on this mother of all bubbles was an unassuming fi gure called
John Paulson. Neither tall nor short, neither handsome nor plain, neither glad-handingly eager nor offensively standoffish, he came across as
Mr. Average. After graduating from Harvard Business School in 1980, he
had progressed from a management consultancy to an early hedge fund
named Odyssey Partners and thence to Bear Stearns, where he worked on
mergers and acquisitions. In 1994 he had launched a tiny hedge fund of
his own, setting himself up in a Park Avenue building that incubated several other hedge-fund start-ups. Over the next decade, Paulson and Company succeeded steadily, growing its capital from $2 million at inception
to $600 million in 2003; then the great hedge-fund asset boom carried
it away, so that by 2005 it was managing $4 billion. Even then, Paulson
kept his profile low. He had only seven analysts on his staff; and although
he had amassed a personal fortune, he had done so in the quietest way
possible.5
Paulson was a loner and a contrarian. He had no doubt of his own
ability and no need for affi rmation. Plowing his own road as a boutiquehedge-fund manager, he had honed the art of the unconventional long
326 MORE MONEY THAN GOD
shot. He specialized, for example, in a form of merger arbitrage that
focused on long odds: As well as investing in mergers that were expected
to be consummated and collecting a modest premium, Paulson sometimes bet against the ones that might blow up, or in favor of ones where
the market might be shocked by a surprise bid from a rival acquirer. Paulson also made money by calling turns in the cycle. When the economy
was booming, he looked for the moment to go short, and vice versa. Some
of the people who worked for him had the same maverick vibe. Paolo Pellegrini, a tall, elegant Italian with heavy-framed glasses and a permanently
amused twinkle in his eyes, had spent years chasing fruitlessly offbeat
ideas; “I’m a romantic type,” he said later.6
When Pellegrini signed on as
Paulson’s analyst for financial companies in 2004, he realized that for the
first time in his life, his unconventional style was welcomed.
Much of Paulson’s skill lay in the detail of his positions. He expressed
his skepticism about booms via a strategy known as capital-structure
arbitrage, which started from the fact that the various bonds issued by
a given company might be treated differently in bankruptcy. So-called
senior bonds had the first claim on the company’s remaining assets and
so would get paid back first; junior bonds made do with whatever was left
over. So long as the company was healthy, investors didn’t focus on this
dull legal nuance, so the senior and the junior bonds traded at similar
prices. But if the economy was weakening, an opportunity arose. Paulson
could assess which companies were heading for bankruptcy—they might
be in a cyclical industry, for example, or they might have too much debt.
Then he could short the junior bonds that would get hit the most if the
company went down, sometimes hedging his position by going long the
senior bonds.
In early 2005, Paulson started to feel that the economic cycle was getting ready to turn downward. Bonds that he had bought at a discount
during the previous recession were now trading at silly heights; fi nancial
markets were frothy thanks to a long period of low interest rates. Paulson
began to hunt for the best way to bet against this bubble. He wanted to
find American capitalism’s weakest spot—the thing that would blow up
the loudest and fastest if the economy slowed even a little. The dream
RIDING THE STORM 327
target would combine all the standard vulnerabilities: It would be in a
cyclical industry, it would be loaded up with too much debt, and the debt
would be sliced into senior and junior bonds, so that Paulson could short
the junior ones, where all the risk was concentrated. Paulson experimented
with shorts on car-company bonds, on the theory that consumers were
taking out car loans that they could not afford. He shorted an insurance
company and a couple of home lenders. But there was a risk in all these
trades. The car companies, insurers, and home lenders all had value as
franchises—they had buildings, brands, customer relationships—so even
if they collapsed under the weight of their debts, they would probably still
be worth something. If Paulson was going to be contrarian, he wanted to
short something that could be totally wiped out. In the spring of 2005, he
hit on the right target.
The target was mortgage securities, which combined every imaginable
charm that a short seller could wish for. Home prices, and therefore mortgages, were certainly cyclical, even though the great American public had
convinced itself that home prices could only go upward. Equally, home
prices were built on huge mountains of household debt, and the moment
that families hit hard times, they would be unable to make their payments. As to the division of junior from senior debt, Paulson had never
seen anything quite like the feast that the mortgage industry served up.
Lenders like Daniel Sadek generated mortgages that were sold to Wall
Street banks; the banks turned these into mortgage bonds; then other
banks bought the bonds, rebundled them, and sliced the resulting “collateralized debt obligation” into layers, the most senior ones rated a rocksolid AAA, the next ones rated AA, and so on down the line to BBB and
lower—there might be eighteen tranches in the pyramid. If the mortgages
in the collateralized debt obligation paid back 95 percent or more of what
they owed, the BBB bonds would be fine, since the first 5 percent of the
losses would be absorbed by even more junior tranches. But once nonpayments surpassed the 5 percent hurdle, the BBB securities would start
suffering losses; and since the BBB tranche was only 1 percent thick, a
nonpayment rate of 6 percent would take the whole lot of them to zero.
In contrast to auto-company bonds, there was no franchise value to worry
328 MORE MONEY THAN GOD
about, either. A bankrupt company might be worth something to someone. A pile of loans with zero payout is worth, simply, zero.
In April 2005, Paulson placed his first bet against these mortgage securities. He bought a credit default swap—an insurance policy on a bond’s
default—on $100 million worth of BBB-rated subprime debt. There was
a huge asymmetry in the risk and the reward: He paid $1.4 million for a
year’s worth of insurance, but if the securities were wiped out, he stood
to pocket the full $100 million. The question was whether the odds of
default were good: You can get a juicy payout by betting on a single number in roulette, but that’s because your chances of winning are abysmal.
To figure out the odds, Paulson turned to Paolo Pellegrini, the offbeat
Italian. Armed with a $2 million research budget, Pellegrini bought the
largest mortgage database in the country, hired an outside firm to warehouse the numbers, and brought in extra analysts to figure out the past
behavior of default rates.
Pellegrini’s first discovery was not encouraging. He and Paulson had
begun by thinking that families with unpayable mortgages were bound to
default. But now Pellegrini saw there was a catch: so long as house prices
continued to head up, homeowners would be bailed out by the option of
refi nancing.7
But Pellegrini made a second discovery as well. The mortgage-industrial complex argued that house prices, which in the summer of
2005 were appreciating at a rate of 15 percent annually, would never fall
across the country in a synchronized way; it had never happened before,
so bonds backed by bundles of mortgages drawn from different states were
regarded as relatively riskless. Because Pellegrini was a newcomer to the
mortgage game, he was unburdened by this article of faith, and his number crunching showed that its basis was shaky. If you adjusted house prices
for inflation, there had been national slumps in both the 1980s and 1990s,
so there was every reason to suppose that the extraordinary run-up of the
early 2000s would be followed by another downturn. Moreover, to block
the option of refinancing, it was not actually necessary for house prices
to fall; if prices merely went flat, home owners would lack the collateral
to take out new and larger mortgages. Pellegrini’s analysis suggested that
zero house-price appreciation would eventually lead to a mortgage default
RIDING THE STORM 329
rate of at least 7 percent, wiping out the value of all BBB bonds. The verdict could be summed up in a phrase: Zero would mean zero.
By early 2006, Paulson’s initial mortgage bets had failed to make money,
and some of his investors were muttering that he had strayed beyond his
competence. But the more Paulson contemplated the results of Pellegrini’s
research, the more he was convinced that he had found the opportunity of
a lifetime. House-price appreciation was slowing as the Fed’s interest rate
hikes pushed up the cost of mortgages, so the odds of flat house prices had
to be at least even: This was like betting on red in a roulette game. But the
potential reward was seventy or eighty times the stake, double the payout
from betting on a single roulette number. Paulson drew up a simple table
to describe what he could do. If he set up a fund with $600 million of
capital and spent 7 percent of that taking out insurance on BBB mortgage bonds, the worst that could happen was a loss of $42 million. The
rewards, on the other hand, were almost limitless. If the BBB bonds suffered a relatively mild default rate of 30 percent, the fund would gain 341
percent, or $2 billion. If they suffered a default rate of 50 percent, it would
gain 568 percent, or $3.4 billion. And if the bonds suffered a default rate
of 80 percent, which Paulson considered highly likely, the fund would
gain 909 percent—an astonishing $5.5 billion. When Paulson explained
this to investors, a few thought he had gone crazy. A gain of 909 percent?
When did that ever happen? But Paulson was not a man to be deterred. In
the summer of 2006, he set up a new hedge fund to do exactly what his
table said, seeding it partly with his own money and enlisting Pellegrini
as the comanager.
The challenge was how to do the trades in the size that he now wanted.
Paulson could bet against mortgage bonds by borrowing them and selling them short, a cumbersome operation. Or he could buy an insurance
policy—a credit default swap from a bank—but that depended upon
finding a bank that was interested in selling. To Paulson’s great good fortune, in July 2006 Wall Street’s top investment banks created an easier
option: Hoping to earn themselves a stream of trading commissions,
they launched a subprime mortgage index, known as the ABX. Paulson
now found that, on any given day, it was easy to buy insurance on, say,
330 MORE MONEY THAN GOD
$10 million of subprime paper. Then, a week or two later, he took a call
from one of the big banks. The man on the line was an ABX trader.
“What’s your picture?” the trader demanded. He was willing to deal
with Paulson in size. How many millions’ worth of subprime bonds did
he want to buy insurance on?
Paulson considered. He didn’t want to scare the trader off. If the guy
knew how much insurance Paulson really wanted, he surely would not be
stupid enough to sell without first moving the price against him.
“Five hundred million,” Paulson ventured.
“Done,” the trader responded.
“Another five hundred million,” Paulson said.
“Done,” the man repeated. He wasn’t flinching in the least. Then he
said again, “Tell us your total picture.”
“Call me again tomorrow,” Paulson said, and the next day he bought
insurance on another $1 billion of subprime bonds. In the first half of the
year, he had hustled to lay his hands on $500 million of this stuff. Now,
in just two days, he had bought four times that quantity.
“Tell us your picture,” the trader said again.
Paulson thought to himself, this is the holy grail. He remembered
Soros’s words: Go for the jugular.
“I’ll do another three billion,” he said.8
At this, there was a silence on
the line. The trader agreed to another billion, then balked at doing any
more. But by calling around the other banks, Paulson established positions totaling $7.2 billion for his credit fund.9
At the end of 2006, he
launched a second fund with the same strategy.
A few weeks after that, the tide turned for Paulson. On the afternoon
of February 7, 2007, New Century Financial Corp., the country’s second
largest subprime lender, made a startling announcement. Its fourth quarter earnings, due out the next day, would have to be postponed because the
fi rm was still calculating losses—a shock given that it had been expected
to report a healthy profit. It turned out that New Century’s subprime
loans were blowing up still faster than the skeptics feared; some of its
borrowers were unable to make their first payments. That same day, the
RIDING THE STORM 331
British bank HSBC, which was the third-largest subprime lender in the
United States, announced that it would have to set aside $10.6 billion in
loan- loss reserves because of busted mortgages.
The following morning, as the share prices of New Century and
HSBC tumbled, Paulson was sitting at his desk when his head trader
informed him that the ABX index had slid five points. Because of his
massive positions, a 1 percent decline in the ABX handed Paulson a profi t
of $250 million; in a single morning he had netted $1.25 billion, about
as much as Soros had earned from his wager against sterling. At the end
of that month, when Paulson reported his February results, his offi ce
received a phone call from an incredulous client.
“Is this a misprint? It’s 6.6 percent, right, not 66 percent?”10
The results were not a misprint. Once house prices stopped appreciating, overindebted families began turning in their keys, so that BBB- rated
mortgage securities were worth practically nothing. Within months New
Century had declared bankruptcy and HSBC had sacked its U.S. executives; but every blow to the mortgage industry was a bonus for Paulson.
On a hot day in the summer, Paulson was in the middle of a meeting
with a pair of potential clients when a colleague came in and whispered
something in his ear. Paulson abruptly excused himself, leaving his guests
in the stuffy conference room. When he returned after a few minutes, he
could not wipe a wide smile off his face. His visitors eventually asked him
if there was somewhere else he needed to be. Unable to contain himself,
Paulson divulged his secret.
“We just got our marks for the day,” he blurted out. “We made a billion
dollars.”11
PAULSON’S MEMORY OF SOROS’S INJUCTION TO GO FOR THE
jugular was more fitting than he realized. The subprime bubble was a
twenty-first-century version of the policy errors that earlier hedge funds
had exploited. In the 1970s, incompetent central banks had stoked inflation, allowing commodities traders to ride glorious trends. In the 1990s,
332 MORE MONEY THAN GOD
central banks had committed themselves to untenable exchange-rate pegs
that macro traders like Soros attacked gleefully. By the 2000s, infl ation and
unsustainable currency pegs were gone; but the passing of these follies made
way for a new one. Because inflation had been vanquished, central banks
felt free to stimulate economies with low interest rates, rendering money
cheap and creating the conditions for an asset bubble. Because exchange
rates were now stable, Wall Street was emboldened to take other sorts of
risk, leveraging itself up and further adding to the bubble. Each new era
brought a fresh kind of blunder, creating a fresh opportunity for traders
too. The heyday of macro hedge funds might be over, but a new heyday of
credit hedge funds had arrived. John Paulson was the new George Soros.
There was another sense in which the Soros memory was relevant. The
famous macro trades had yielded extraordinary profits because there were
willing suckers on the other side—in 1992, it was the British government.
Equally, Paulson’s subprime mortgage trade required a sucker: He could
only build vast short positions on mortgages if somebody else was buying
them. Of course, the mystery was who these buyers were—and why they
were so eager to throw away their money.
When the mortgage bubble burst in 2007 and 2008, extraordinary
losses cropped up all over the financial system. Daniel Sadek’s handiwork,
and millions of other loans that smelled equally putrid, had been packaged
and sold to investors from Japanese insurers to Norwegian pension funds.
Inevitably, some hedge funds were caught holding subprime garbage too;
a couple of medium-sized outfits called Peloton Partners and Sailfi sh
Capital sank under the weight of mortgages. Peloton, in particular, was
hardly a model of financial prudence: Its London-based managers became
famous when their secretary stole £4.3 million from their accounts without their realizing that anything might be amiss, though they told the jury
at her trial that their bank account felt “one or two million light.” Still, by
any reasonable reckoning, the hedge-fund sector as a whole survived the
bubble extraordinarily well: By and large, it avoided buying toxic mortgage securities and often made money by shorting them. In 2007, hedge
funds specializing in asset-backed securities, a category including mortgages, were up 1 percent on average, according to Hedge Fund Research,
RIDING THE STORM 333
a data provider in Chicago—in other words, they completely dodged the
subprime bullet. Meanwhile, hedge funds as a whole gained 10 percent
during the year—not bad for a crisis.12
If hedge funds mostly recognized subprime assets for the garbage that
they were, who did lead the buying? The answer, to a large extent, was
banks and investment banks—firms such as Citibank, UBS, and Merrill
Lynch. On first inspection, this seems strange. These firms were proud of
the trading desks that managed their proprietary capital. And yet, unlike
hedge funds, the banks and investment banks bought subprime mortgages
by the bucketful. Citibank’s losses were so astronomical that the U.S. government was forced to rescue it, buying more than a third of its shares. UBS
ended up needing a lifeline from the Swiss government. Merrill sold itself
to Bank of America to avoid going down. And whereas the failure of hedge
funds such as Peloton and Sailfish—like the earlier failure of Amaranth—
cost taxpayers nothing, the failure of Citi and its peers imposed enormous
burdens on government budgets and the world economy.
Why this stark contrast with hedge funds? There are four principal
reasons, and they begin with regulation. Banks that take deposits, such as
Citi and UBS, are required by regulators to hold a minimum amount of
capital in order to shore up their solvency. This should have made the banks
more resilient than hedge funds when the mortgage bubble imploded. But
capital requirements, while necessary, can become a crutch: Rather than
running their books in a way that rigorous analysis suggests will be safe,
banks sometimes run their books in a way that the capital requirements
deem to be safe, even when it isn’t. Subprime mortgages presented a classic example of this problem. Bonds backed by toxic mortgages were given
the top (AAA) rating, partly because the rating agencies were paid by the
bond issuers, which dulled the incentive to be critical. Once the AAA seal
of approval was affixed to subprime assets, banks were happy to hold them
because capital requirements allowed them to do so without putting aside
much capital. Regulation and ratings agencies thus became a substitute
for analysis of the real risks in mortgage bonds.13 Because hedge funds are
in the habit of making their own risk decisions, undistracted by regulation
and ratings, they frequently fared better.
334 MORE MONEY THAN GOD
If capital standards turned out to be a mixed blessing, the second problem hinged on incentives. Hedge-fund incentives are not perfect. The
managers keep a fifth of the profit in a good year but don’t give back a
fifth of their losses in a bad year; therefore they may be tempted to gamble
recklessly. But hedge funds have a powerful advantage. Their managers
generally have their own wealth in their funds, which gives them a strong
reason to control risks effectively. By contrast, bank proprietary traders do
not risk their personal savings in the pools of money that they manage.
Instead, bank traders often own company stock. But the value of that
stock is driven by a variety of different profit centers within the bank. If
the prop desk loses money, its errors will be diluted by the other business
lines. The stock may react marginally or not at all. The effect is too weak
to change prop traders’ incentives.
This contrast points to a third reason why the banks fared poorly in
the credit bubble: Those multiple profit centers distracted executives. The
banks’ proprietary trading desks coexisted alongside departments that
advised on mergers, underwrote securities, and managed clients’ funds;
sometimes the scramble for fees from these advisory businesses blurred
the banks’ investment choices. Again, the subprime story illustrated this
problem. Merrill Lynch is said to have sold $70 billion worth of subprime
collateralized debt obligations, or CDOs, earning a fee of 1.25 percent
each time, or $875 million. Merrill’s bosses obsessed about their standing in the mortgage league tables: The chief executive, Stan O’Neal, was
prepared to finance home lenders at no profit in order to be first in line
to buy their mortgages.14 To feed their CDO production lines, Merrill
and its rivals kept plenty of mortgage bonds on hand; so when demand
for CDOs collapsed in early 2007, the banks were stuck with billions of
unsold inventory that they had to take onto their balance sheets. The
banks therefore became major investors in mortgages as an unintended
by-product of their mortgage-packaging business. When the scramble for
commissions distorts investment choices in this way, it is hardly surprising
that the investment choices are horrendous.
The final explanation for the banks’ fate hinges on their culture.
Hedge funds are paranoid outfits, constantly in fear that margin calls
RIDING THE STORM 335
from brokers or redemptions from clients could put them out of business. They live and die by their investment returns, so they focus on them
obsessively. They are generally run by a charismatic founder, not by a committee of executives: If they see a threat to their portfolio, they can flip
their positions aggressively. Banks are complacent by comparison. They
have multiple streams of revenue and their funding seems secure: Deposit-taking banks have sticky capital that enjoys a government guarantee,
while investment banks felt (wrongly, as it turned out) that their access
to funding from the equity and bond markets made them all but impregnable. The contrast between hedge-fund paranoia and bank complacency
emerged most clearly in the years after Russia’s default and the Long-Term
Capital crisis in 1998. For the most part, hedge funds responded to that
shock by locking up investors for longer periods and negotiating guarantees from brokers to stabilize their capital. Meanwhile, banks trended
in the opposite direction: Their buffers of equity capital fell by about a
third between the mid-1990s and the mid-2000s. Even in 2006 and 2007,
when the mortgage bubble was bursting, many banks were too sluggish
to adjust. They sold John Paulson billions of dollars of mortgage insurance via the new ABX index, but they did not stop to ask themselves what
Paulson’s buying might tell them.
The contrast between banks and hedge funds was summed up by the
story of Bear Stearns, even though there was a twist to it. Bear Stearns had
a reputation as a vigilant manager of its trading risks; it was exactly the
kind of institution that would not be expected to buy poisonous mortgage
securities. But by the mid-2000s, Bear had emerged as the number one
packager of mortgage-backed securities on Wall Street, up from the third
slot in 2000; and to keep the sausage factory going, Bear had bought up
subsidiaries that made subprime loans directly to home buyers, both in
the United States and in Britain. Inevitably, this expansion shifted managers’ attention: They were less focused on what mortgages might be worth
than on how to create lots of them. Meanwhile, in 2003, Bear devised an
ambitious “10 in 10” strategy for its asset-management division: Revenues
and profits from this unit would rise to 10 percent of Bear’s total by the
year 2010, never mind the fact that Bear’s asset-management subsidiary
336 MORE MONEY THAN GOD
was starting down this road from a position of insignifi cance. Again,
this pursuit of fee income helped to seal Bear’s fate. The bank hurriedly
assigned unqualified executives to build out its asset-management business by launching internal hedge funds, and some of these funds loaded
up on subprime debt. That misjudgment set Bear on the path that led to
its collapse the following year—and to the Federal Reserve being forced
to absorb $29 billion of Bear’s toxic securities.
The failure of Bear’s internal hedge funds could be seen as evidence of
hedge funds’ riskiness. But the truth is that the Bear funds were a product
of bank culture, not hedge-fund culture. Like other hedge funds launched
under the umbrella of large banks, the Bear funds were managed by people
who were seeded within a large firm, not by entrepreneurs who launched
independent ventures. They raised capital with the help of the parent bank’s
network and brand, which lowered the barriers to entry that freestanding
hedge funds must reckon with. They knew that if they failed, the parent
bank might bail them out, softening their vigilance. The investment thesis
of the Bear funds underlined their close ties to the mother ship. Two of the
funds were run by Ralph Cioffi, who had previously worked on Bear’s sales
desk, peddling mortgage-backed securities to institutional clients. His plan
for his hedge funds was to buy those same mortgage-backed securities and
leverage them up by an astonishing thirty-five to one. This was the sort of
risky bet that made sense to a deep-pocketed, fee-hungry parent. It would
have been less likely to fly with a real hedge fund.
Ralph Cioffi himself was not the sort of figure who could have launched
his own hedge fund easily. As a salesman, he had virtually no experience
in controlling portfolio risk—indeed, some Bear executives argued that
he should not be allowed to do so. Paul Friedman, the COO of Bear’s
fi xed-income desk, said afterward, “There were a fair number of skeptics
internally who couldn’t figure out how this guy—who was bright but had
never managed money—was now going to be running money. He knew
nothing about risk management, had never written a ticket in his life that
wasn’t someone else’s money.”15 Likewise, Cioffi was short on managerial ability: In a brief stint as a supervisor, he had performed disappointingly. Even with Bear smoothing the way, Cioffi had trouble handling the
RIDING THE STORM 337
administrative challenge of running a hedge fund. He failed to secure the
approval of his fund’s independent directors before buying securities from
other divisions of Bear Stearns. The paperwork was in such a disastrous
state that a law firm had to be brought in to investigate. In a complaint
that summed up the trouble with hedge-fund subsidiaries within banks,
an investor protested that it had put money in Bear’s funds because of the
parent firm’s reputation for managing its own risks and claimed that Bear
treated outside clients differently.16 The truth was that Bear and other
banks that jumped onto the hedge-fund bandwagon were less intent on
risk management than on leveraging their brands. If you wanted a reason
why John Paulson made billions from the mortgage bubble and his former
employer went out of business, the non-hedge-fund character of Bear’s
internal hedge funds came close to supplying it.17
In June 2007, Cioffi’s leveraged subprime mortgage funds blew up.
They had been marketed on the strength of the Bear Stearns brand, so now
Bear felt obliged to rescue them with an emergency loan— vindicating
the view that deep-pocketed parents dull the incentive to be vigilant.
Meanwhile, Paulson’s mortgage wager generated the biggest-ever killing
in the history of hedge funds. By the end of 2007, his fl agship mortgage fund was up a cumulative 700 percent, net of fees.18 His company
generated an estimated $15 billion in profits, and Paulson himself pocketed between $3 billion and $4 billion—he was “the man who made too
much,” according to one magazine profile. The following year, when Paulson recommended changes to Treasury secretary Hank Paulson’s bank
bailout plan, his reception in Congress recalled the deference that Soros
frequently enjoyed. “I was thinking we probably had the wrong Paulson”
in charge, remarked Representative John Tierney of Massachusetts.
Yet if Bear’s failure and Paulson’s triumph constituted a victory for
hedge funds, it was too early to be sure that they would survive the shocks
that followed.
THE MONTH AFTER THE BEAR FUNDS FAILED, KEN GRIFFIN
of Citadel headed off to France on vacation. He was a man in his prime.
338 MORE MONEY THAN GOD
His formidable firm occupied a landmark tower in Chicago’s downtown
business district. He had paid $80 million for a painting by Jasper Johns.
He had recently married his French bride at the Hameau de la Reine in
Versailles, the eighteenth-century mock village where the young Queen
Marie Antoinette had once played peasant. But in the summer of 2007,
Griffin found his vacation impossible to enjoy. Every day began with phone
calls back to Chicago and ended the same way, and by Friday morning,
Griffin had had enough. “Don’t take this the wrong way,” he told his wife.
“You can come or you can stay. I’m going.”19
That Friday, July 27, was the day when the subprime troubles morphed
into a larger credit crisis. Loans from guys who catapulted Porsches,
byzantine collateralized debt obligations with eighteen layers, the whole
pyramid of side bets on the ABX index—until just recently, all could be
dismissed as a mania confined to one corner of the markets. But that
Friday a Boston-based hedge fund named Sowood Capital Management
began to catch fire. Its $3 billion portfolio was down sharply, and it was
starting to receive margin calls from brokers.20
The remarkable thing about this development was that Sowood had
avoided subprime securities. Its boss, Jeffrey Larson, had made his reputation working for the Harvard endowment, which had matched Yale’s
enthusiasm for absolute return by creating its own stable of in-house
hedge-fund managers. By the end of his twelve-year stint with Harvard,
Larson had been running $3 billion of the $20 billion endowment. Then
in 2004 he had persuaded Harvard to seed an independent multistrategy
fund. The new firm, Sowood, had acquired about seventy employees. It
had notched up gains of 10 percent annually in its first three years, largely
by focusing on credit markets.
At the start of 2007, Larson had rightly sensed that default rates might
be heading upward. In a version of the capital-structure arbitrage that
John Paulson favored, he bought relatively safe “senior” bonds and shorted
riskier paper, positioning himself to do well in a downturn. The subprime
losses that buffeted Bear Stearns did not appear to threaten him and might
even be good news. In early July, Larson injected another $5.7 million of
his personal savings into Sowood.21
RIDING THE STORM 339
Soon after that, Larson was forced to reckon with his error. Other
leveraged players that had lost money in mortgages were raising capital by
dumping nonmortgage positions; and in the third week of July, Sowood’s
holdings of corporate bonds began to suffer serious losses. High-quality
bonds that were supposed to be fi ne in a downturn were often the easiest
to sell, so they were dumped first; when traders deleveraged indiscriminately, the logic of capital-structure arbitrage went out the window. Larson
turned to his old mentors at Harvard, hoping for an emergency injection
of capital; Harvard decided that would be too risky. By the morning of
Friday, July 27, the news of Sowood’s troubles had spread around Wall
Street, and traders began to position themselves for a contagious spiral.
Margin calls might force Sowood to dump its corporate-bond portfolio
in a fire sale, hitting other bond funds, triggering more sales and driving
the market downward. Of course, these fears were self-fulfi lling, and the
bonds fell hard that afternoon. Sowood was hemorrhaging money, and
even when the market closed for the weekend, the fund continued to get
hit in after-hours trading.
Around lunchtime on Sunday, Jeff Larson placed a call to Ken Griffi n.22 Larson recalled how Citadel had bought Amaranth’s trading book
the previous year. He asked whether Griffin might want to do the same
for Sowood’s portfolio. The sooner Sowood could find a buyer, the sooner
it could stop predators from targeting its positions. Larson needed a deal
before the markets opened the next morning.
Griffi n got on the phone to his lieutenants. Gerald Beeson, one of the
two executives who had parachuted into Amaranth, had just started his
own vacation on a beach near Chicago. He drove back at top speed, dialing several colleagues on the way; he stopped off at home to throw on
some long pants and raced to the airport. By around seven o’clock that
evening, half a dozen Citadel officials had taken over a conference room
at Sowood’s offices in Boston, where they discovered that Sowood had
also summoned Morgan Stanley. As the two teams examined Sowood’s
portfolio, it quickly became clear that many of the positions were diffi cult
to value; they consisted of derivatives that were traded “over the counter”
between companies, rather than on a transparent, centralized exchange,
340 MORE MONEY THAN GOD
so only a firm that traded all these instruments itself had a hope of fi guring
out the going rate for them. Sowood’s tangle of legal arrangements with
brokers and trading partners had to be assessed. The data that described
its trades had to be uploaded into the buyer’s systems.
At around 9:00 p.m., the head of the Morgan team called Griffin in
Chicago.
“Ken, we’ll pick this up in the morning.”
“We’ll get this done by then,” Griffin answered. He heard a noise on
the line. He wasn’t sure if the other guy was laughing at him.
By 7:00 a.m. on Monday, Griffin had done what he had promised. He
and his team had worked through the night and bought Sowood’s entire
trading book. Jeff Larson explained to his investors that “Citadel offered
the only immediate and comprehensive solution.” Sowood’s two funds
were down 57 percent and 53 percent for the month; Harvard’s endowment had taken a $350 million hit; but at least the nightmare had now
ended.23 The deal was announced publicly, calming the fear that Sowood
might dump its positions. The bond market recovered more than 4 percent that day, and the panic was over. One hedge fund had imploded,
threatening to start a systemic fi re. Another hedge fund had swooped in,
acting as the fi reman.
Almost immediately, a new fi re started.
THE NEXT FRIDAY, AUGUST 3, A RATINGS AGENCY ANnounced that Bear Stearns’s debt might be downgraded. It was the first
time a Wall Street fi rm’s financial health had been questioned in the crisis,
and Bear Stearns’s stock fell so hard that its bosses convened a conference
call in an attempt to calm investors. More than two thousand people
dialed in, but there was no calming effect at all. Bear’s chief financial officer blurted out that the credit markets were behaving in the most extreme
manner he had witnessed in his long career; “he fucking blew the market
up,” Bear’s treasurer said sweetly.24 On CNBC a few hours afterward,
the financial pundit Jim Cramer fanned the flames. “It is time to get on
RIDING THE STORM 341
the Bear Stearns call!” he ranted, excoriating the Fed for sitting on its
hands. “We have Armageddon.”25
Cramer could not guess where the next fire would come from. But away
on the sidelines of the subprime drama, quantitative hedge funds were
starting to sense trouble. In the second half of July, computerized systems
that traded equities were no longer performing well, and some were even
losing money. As the quants analyzed the problem, they discovered something disturbing. It was not that a new risk was swamping the buy and
sell signals that had been profitable for years; the signals themselves were
no longer working. The quants had programs that bet on momentum in
stock prices; programs that bet that momentum would reverse; and programs that bet that cheap stocks with low price-to-earnings ratios would
outperform expensive ones.26 All these bets were fizzling at once. Somewhere out there in the trading universe, one or maybe several quants were
liquidating their holdings, perhaps because they had lost money on their
mortgage bets and needed to raise cash. Their forced selling was driving
prices against anyone who had a comparable portfolio.27
At the end of July, Mike Mendelson, a hard-charging ex-Goldman
quant, decided it was time to cut the risk in his trading book. Mendelson now worked for AQR, an investment company set up in 1998 that
managed $10 billion of capital in hedge funds and another $28 billion
in traditional ones. AQR’s chief founder, Cliff Asness, had contributed
to the academic literature on pricing anomalies in stocks; having programmed his computers to milk these effects, he delivered steady, uncorrelated returns while also sleeping soundly. Although AQR’s losses in late
July had been too modest to disturb anybody’s rest, Mendelson had heard
that another big quantitative fund had suffered a bad loss. Erring on the
side of prudence, he trimmed leverage. Then, in the fi rst days of August,
AQR’s models started to work again. Whoever had been liquidating quant
positions must now have stopped. The trouble seemed to be over.
On Monday, August 6, Mendelson sat through some routine meetings
at AQR’s office, a utilitarian suite in a featureless building just by Greenwich station. Around midmorning, he strolled out to the local Subway
342 MORE MONEY THAN GOD
sandwich store, and as he waited in line he checked his funds’ performance on his BlackBerry. He peered for a few seconds at the screen. The
numbers were all red, and they were not small, either. In the past three
hours, AQR had lost tens of millions of dollars.28
“Oh, God, this is ridiculous,” Mendelson thought to himself. Some
quant somewhere must be deleveraging, but on a monstrous scale. Or
maybe several quants were bailing all at once? How long could this
go on?
The one thing Mendelson knew was that he would have to cut leverage quickly. If a fund has $100 of capital to support $800 of positions,
a 5 percent loss will leave it with $60 in capital and $760 worth of positions: Its leverage rockets up from eight to one to more than twelve to
one.29 If there is another 5 percent loss the next day, the leverage will not
merely rise another 50 percent; it will practically triple, from twelve to
one to thirty-three to one. A third 5 percent setback will drive leverage
to infinity and beyond, since the fund’s capital will be negative. Back in
AQR’s offices, Mendelson and his colleagues sketched a hyperbolic curve
on a notepad, showing how leverage could accelerate upward. The only
way to survive was to keep leverage on the flattish, left-hand portion of the
curve. If AQR’s funds were down 5 percent, they might have to sell almost
two fifths of their positions to keep leverage stable. Otherwise they would
begin a death spiral.
Meanwhile, versions of this drama were playing out at other quantitative hedge funds. Most were not like Jim Simons’s Medallion: They
were trading well-known price anomalies, not esoteric secrets; “there is
no E=MC2
under the hood,” as Asness put it.30 Even Simons confessed
that his large fund for institutional investors traded on signals that were
understood by others; everyone had read the same academic papers, had
looked at the same data, and was making the same types of bets, especially on stocks with momentum and value.31 In normal times, this didn’t
matter: Even if an army of funds was chasing “value,” there were dozens
of ways to measure this phenomenon, so crowding was limited. But as
with all investment strategies, crowding did turn out to matter during a
panic: Selling by one big fund caused losses at other ones, especially since
RIDING THE STORM 343
quantitative strategies had grown large enough to shove prices around.32
Once rival funds started to incur losses, the logic of the hyperbolic curve
would force them to sell too. By Monday afternoon, Mendelson began to
see how bad things could get. Not only would AQR have to sell a huge
chunk of its positions to keep its leverage stable in the face of initial losses.
As its competitors sold too, it would have to sprint to stay still, racing
other quants to cut the size of its portfolio.
The next day was even more brutal than Mendelson had expected.
AQR’s models lost money twice as quickly as on Monday, and the fi rm
instructed its computers to dump billions of dollars’ worth of positions.
The good news was that technology made it possible to liquidate a portfolio much faster than in earlier years; the bad news was that AQR’s rivals
could liquidate just as quickly. Every quant was firing off torpedoes at
every other quant; there were rumors of funds that were down 10 percent
or worse. At the Renaissance campus in Long Island, Jim Simons huddled
with his top lieutenants in front of the computer screens, tweaking the
parameters on his models like a pilot navigating a hurricane. Cliff Asness,
AQR’s founder, blew up in the office and smashed computer screens.33 He
took a call from Ken Griffin, who by now had a reputation for buying the
corpses out of car wrecks. “I looked up and saw the Valkyries coming and
heard the grim reaper’s scythe knocking on my door. I did my best to run
to the light,” Asness said later.34
While this chaos unfolded, policy makers appeared to occupy a parallel universe. On Tuesday, August 7, the second day of the quant quake,
the Fed’s interest-rate committee issued a warning about the risks of infl ation. The next day President Bush visited the Treasury to meet with his
economic advisers. “[I]f the market functions normally, it will lead to
a soft landing,” he said hopefully. On Thursday the tone from Washington began to change, but less because of the carnage at quantitative
funds than because of trouble from Europe: The giant French bank BNP
Paribas had suspended redemptions from three internal money-market
funds, citing “the complete evaporation of liquidity.” Subprime losses were
clearly scaring the markets, and the European Central Bank responded
with $131 billion in emergency liquidity. By Thursday afternoon, the
344 MORE MONEY THAN GOD
Fed’s chairman, Ben Bernanke, had turned his office into a makeshift war
room, and his chief lieutenants dialed in from various vacation locations.
Early the next morning, the Fed reversed its earlier emphasis on infl ation,
pledging to provide enough cash “to facilitate the orderly functioning of
fi nancial markets.”
Meanwhile in Greenwich, Mendelson was starting to see light at the
end of the tunnel. It had nothing to do with the Fed’s U-turn and everything to do with other hedge funds. Starting on Tuesday, Mendelson had
begun to call brokers and friends in the markets—anybody who might
know anything about how other leveraged quant funds were positioned.
The business was dominated by a handful of firms. There was Jim Simons’s
new fund, which ran more than $25 billion of institutional money. There
was Highbridge Capital, a subsidiary of J.P. Morgan. There were D. E.
Shaw, Barclays Global Investors, and Goldman Sachs Asset Management.
Mendelson wanted to know how much the big players had cut leverage
so far: If they got themselves down into the flat part of the hyperbolic
curve, the selling pressure would end and the storm would be over. After
working the phones all day Tuesday, Mendelson reached a buddy just after
midnight. The guy had rushed back early from vacation and was falling
apart: He was exhausted, blabbering, at the end of his tether. Mendelson
could tell he was about to liquidate his whole book. He ticked one fi rm off
his list and hit the phones again the next morning.
By Thursday evening, Mendelson had figured out that only one big
player had yet to cut leverage. He guessed it might be one of the hedgefund subsidiaries of his old firm, Goldman Sachs: the $5 billion Global
Equity Opportunities Fund. Goldman’s executives had decided that the
fund’s positions were too big to sell, so its leverage had rocketed up as
its bets got hammered. When the market opened on Friday, one of two
things would happen. Either the fund would liquidate, hitting other quant
funds for a fifth straight day. Or it would be recapitalized by its parent
company.35
When Friday morning came, Mendelson could not care less about the
Fed’s stance on inflation. He was looking at his own trading model. Within
a few minutes, it was generating profits—its performance practically
RIDING THE STORM 345
screamed out that the Goldman subsidiary had been rescued and that
the quant liquidations had ended. Acting on that signal, AQR began to
releverage as quickly as possible; the more it could catch the upswing as
money flooded back, the more it could make up for the past four days
of carnage. The following Monday, Goldman Sachs announced publicly
what Mendelson had already guessed. It had recapitalized the Global
Equity fund with $3 billion in fresh money.36
The quant quake of August 2007 ended as abruptly as it had started.
Friday and Monday were great days for the models, and most of the
quants recouped at least part of their losses. But the drama prompted a
new round of debate about hedge funds, and the agonizing outlasted the
disruption in the markets. Granted, Amaranth and Sowood had been rescued by a fellow hedge fund, making it hard to argue that the sector was
destabilizing. Granted, hedge funds—or at least, nearly all freestanding
hedge funds—had dodged the mortgage bullet, suggesting that they were
better money managers than their banking rivals. But the storm in the
equity market was surely a warning. The most sophisticated hedge funds
had lost control of their models. The rocket scientists had blown up their
rockets.
The most persuasive critics came from within the hedge-fund establishment. Andrew Lo, an MIT professor who ran his own hedge fund,
published a widely cited postmortem on the quant quake; and Richard
Bookstaber, an MIT alumnus who had worked at several major funds,
pressed the warnings he had recently published in a pessimistic book on
fi nance.37 Lo and Bookstaber contended that the rise of leveraged hedge
funds created a new threat: Trouble in the mortgage or credit markets
could saddle a multistrategy fund with losses, forcing it to liquidate equity
holdings; distress could leap from one sector to the next; the financial
system as a whole was riskier. Lo and Bookstaber linked this warning
to a gloomy view of hedge funds’ investment performance. There were
too many quant funds chasing small market anomalies. This crowding
diminished investment returns, which in turn drove hedge funds to use
dangerous amounts of leverage to maintain profi ts.
There was some truth in all this pessimism. During the LTCM crisis,
346 MORE MONEY THAN GOD
credit markets had been in turmoil but quantitative equity funds had been
fine; the rise of leveraged traders helped to explain why the fire had jumped
the fire wall this time.38 But it was one thing to say that crowding was a
problem in moments of turmoil, quite another to assert that it was forcing
down returns in the good times and making dangerous leverage inevitable. Lo’s paper presented the returns from one quantitative strategy—buy
stocks that are doing badly and sell ones that are doing well—and made
much of the fact that profi ts from this simple contrarian model had deteriorated since 1995, apparently substantiating the case that hedge funds
had no choice but to employ more scary leverage. But basic contrarian
strategies were not central to the quant quake, because the quants themselves could see that there were limited profits in them. The big money in
quant funds was in other strategies—for example, sell expensive growth
stocks with high price-to-earnings ratios and buy cheap, dowdy ones with
low ratios. The price gap between growth stocks and value stocks had
shown little sign of narrowing in the years leading up to 2007; as Asness
put it, “We are fond of saying that if these strategies are truly horribly
overcrowded, then someone has apparently forgotten to tell the prices.”39
Other quants made versions of the same point. Marek Fludzinski, the
head of a hedge-fund company called Thales, tested virtually identical
trading strategies to see if the presence of one of them would erode the
other one’s returns; remarkably, it did not, suggesting that crowding was
not actually a problem.40 It was true that uncrowded bets could suddenly
feel intensely crowded in a moment of turmoil; but this held for virtually
all trading strategies, not just quantitative ones. “Of course, ‘good investing gets clocked as some investors rush for exits’ is not as catchy a story as
‘quant brainiacs follow their computers to a well-deserved doom,’ so I’m
probably not going to win this battle in the media,” Asness lamented.41
If quant strategies were not as crowded as the critics suggested, and if
scary amounts of leverage were therefore not inevitable, what of the charge
that hedge funds increased the risk of broad systemic blowups? Here too
the Lo-Bookstaber critique needed to be qualified. During the fi rst three
days of the quant quake, the signals in the traders’ models performed
abysmally, but the broader market remained calm—the average American
RIDING THE STORM 347
household with its nest egg in an index fund would have noticed nothing,
undermining the notion that this was a crisis for the whole fi nancial system. On the fourth day of the quant quake, the market did suffer a hard
fall, but this reflected the crisis in the credit markets more than the tremors
in quant land. The great thing about liquidating so-called market-neutral
strategies was that the effect on the overall market was neutral: For every
stock the quants sold, they covered a short position. It was true that if
Goldman Sachs had not rescued its subsidiary, the deleveraging would
have lasted longer, potentially forcing multistrategy funds to dump positions in other markets and spreading the trouble. But the way things
actually turned out, the market punished overleveraged traders while the
broader system suffered little harm. This was how capitalism was meant
to discipline its children. No regulator could have done better.
In the final analysis, it was hard to disagree with Mike Mendelson’s
verdict on the quant quake: “A bunch of us lost a bunch of money and had
a really tiring week, which sucked, believe me. But I don’t think it was a
big public policy issue.”42
