Roger Lowenstein, “When Genius Failed: The Rise
& Fall of Long-Term Capital Management” Random House 2000, 236 pps
I have probably read over 30 books
dealing with the financial crisis of 2008, and in most of that reading there is
some reference to the 1998 failure of Long Term Capital Management (LTCM) and
the contributions to that failure by its founder, John Meriwether. So, even though I thought such a relatively
old event had little to teach me about the current crisis, I read it
anyway. Much to my surprise, the reading
experience of this book is much like reading about more recent failures such as
Lehman’s. It becomes evident to me that
the rewards of the financial industry are such that the lessons of these past
failures are affordably best ignored for the players; at least as long as they
can continue to privatize the profits and socialize the losses. The dramatic story of LTCM’s fall is a
chilling harbinger of the crisis that would strike all of Wall Street, from
Lehman Brothers to AIG, a decade later. In his new Afterword, Lowenstein shows
that LTCM’s implosion should be seen not as a one-off drama, but as a template
for market meltdowns in an age of instability—and as a wake-up call that Wall
Street and government alike tragically ignored.
Tragic--at least for the taxpayers; not so much for those that kept the
proceeds.
The financial industry approach to
investment using computer modeling has been, and still is, based on the
Black-Scholes Option model. This model
at the beginning of 1998 predicted that the probability of LTCM to lose all its
capital in one year would be a statistical freak occurring one in every ten to
the twenty-fourth power times—a so-called ten-sigma event.
When it was founded in 1993,
Long-Term was hailed as the most impressive hedge fund in history. When LTCM crashed they had positions in
securities with over a trillion dollars of face value. At the time, many
investment banks were losing hundreds of millions of dollars on similar market
bets. There was concern at the US Federal Reserve that if LTCM defaulted on
their contracts it would cause chaos and a market crash. This in turn could
place the US economy in danger. So the Fed organized a bail-out. A consortium
of banks and trading houses put four billion dollars into LTCM. In return the
consortium took possession of LTCM's market positions. The investors that had
money in LTCM got ten cents on their invested dollar. The partners were largely
wiped out. Once LTCM's market positions were unwound the rescue consortium made
money on their investment. LTCM's
mistakes were made fatal by massive leverage and lack of liquidity. If not for
their huge leverage, LTCM could have survived these mistakes, or at least
survived without such breathtaking losses.
At least this failure was not paid for by taxpayers, unlike 2008.
In the epilogue Lowenstein
summarizes LTCM's losses:
Investment LOSS
Russia and other emerging markets $430
million
Directional trades in developed countries (such as
shorting Japanese bonds) $371 million
Equity pairs trading $286
million
Yield-curve arbitrage $215
million
Standard & Poor's 500 stocks $203
million
High-yield (junk bond) arbitrage $100
million
Interest swaps $1.6
billion
Equity volatility bets $1.3
billion
My Notes:
Pg. xiii: On September 23, 1998 the chiefs of Bankers
Trust, Bear Stearns, Chase Manhattan, Goldman Sachs, J.P. Morgan, Lehman
Brothers, Merrill Lynch, Morgan Stanley Dean Witter, and Salomon Smith Barney
gathered in the New York Federal bank to consider a rescue of LTCM. Joining them were the chairman of the New
York Stock Exchange and representatives from major European banks. LTCM was on the brink of failing. For four years LTCM had been the envy of Wall
Street. The fund had racked up returns
of more than 40 percent a year, with no losing stretches, no volatility,
seemingly no risk at all. This fund had
amassed $100 billion in assets, virtually all of it borrowed—borrowed from the
bankers now gathered. Along with this
massive indebtedness was the additional problem of the thousands of derivative
contracts, which had endlessly intertwined LTCM with every bank on Wall
Street. These contracts, essentially
side bets on market prices, covered more than $1 trillion worth of
exposure. If LTCM defaulted, all of the
banks in the room would be left holding one side of a contract for which the
other side no longer existed.
Pg. 24: As far as securities law is concerned, there
is no such thing as a hedge fund. In practice, the term refers to a limited
partnership, at least a small number of which have operated since the 1920s;
they are private and largely unregulated investment pools for the rich. In return for this freedom from regulation,
the funds must limit access to a select few investors. By law, funds can sign up no more than
ninety-nine investors, people, or institutions each worth at least $1 million,
or up to five hundred investors, assuming that each has a portfolio of at least
$5 million. Presumably, millionaires
know that they are doing; if not, their losses are nobody’s business but their
own.
Pg. 27: Meriwether planned to initially raise a
colossal $2.5 billion to start his fund.
Everything about LTCM was ambitious.
Its fees would be considerably higher than average at 25 percent of the
profits, in addition to a yearly 2 percent charge on assets. (Most funds took 20 percent of profits and 1
percent on assets.) Moreover, the fund
insisted that investors commit for at least three years, an almost unheard-of
lockup in the hedge fund world. To
better attract investors, Meriwether recruited professors Merton and Scholes to
the fund, each said to be on the shortlist of Nobel candidates. He also hired David Mullins, vice chairman of
the Federal Reserve and second in the Fed’s hierarchy to Alan Greenspan, the
Fed chairman. LTCM opened for business
in February 1994 with $1.25 billion—well short of J.M’s goal but still the
largest start-up ever.
Pg. 42: By leveraging one security, investors
potentially give up control of all of their others. So, although their securities might be
unrelated, because they and many other investors owned them, they implicitly
linked them in times of stress. And when
armies of financial soldiers are involved in the same securities, borders
shrink. The very concept of safety
through diversification—the basis of LTCM’s security—would become meaningless. The
real culprit in most financial crisis is leverage, not liquidity. Whenever markets plunge, investors are
stunned to find that there are not enough buyers to go around. The mistake is in thinking that markets have
a duty to stay liquid or that buyers will always be present to accommodate
sellers. If you aren’t in debt
(leveraged), you can’t go broke and can’t be made to sell, in which case
liquidity is irrelevant. But a leveraged
firm may be forced to sell, lest fast-accumulating losses put it out of
business.
Pg. 63: Notice that there is a key difference between
a share of IMB (or an infectious disease) and a pair of dice. With dice, there is risk—you could, after
all, roll snake eyes—but there is no uncertainty, because you know (for
certain) the chances of getting a 7 and every other result. Investing confronts us with both risk and
uncertainty. There is a risk that the
price of a share of IBM will fall, and there is uncertainty about how likely it
is to do so. So many variables—political,
economic, managerial, competitive factors—can affect the result that the
uncertainty all but overwhelms us.
Pg. 68: The LTCM professors computer model treated
the volatility of a security like an inherent unchanging trait. You or I might assume that the market
fluctuations of so many yesterdays are so much noise—arbitrary, not necessarily
likely to recur, and best forgotten. But
to Black, Scholes, and Merton—and to LTCM—these fluctuations were invested with
deep predictive significance. Each tick
of the market up or down was viewed as latent with an unerring forecast of
future risk. This implied that markets
were efficient and rational at every step.
Merton carried the assumption a step further. He assumed that volatility was so constant
that, for example a share of IBM, would never plunge directly from 80 to 60
but would always stop at 79 ¾, 79 ½,
etc., along the way. Therefore at each
infinitesimal moment, traders would readjust the price of option on IBM keeping
them in synchrony with the price of the stock.
And traders who owned both could—by nimbly buying or selling—keep their
portfolio in a risk-free state of balance.
This assumption may approximate real markets when they are calm—but only
then.
Pg. 72: There is a reason why financial markets run
to extremes more often than coin flips.
The coin doesn’t remember that it landed on tails three times in a row;
the odds on the fourth flip are still fifty-fifty. But market trends will sometimes continue
just because traders expect (or fear) that they will. Black-Scholes model assumes a rational
efficient market without the human element that so often, in real life,
overwhelms the market. Even the Federal
Reserve was endorsing such programs at the time of LTCM; these programs went by
the generic name “Value-at-Risk.”
Pg. 102: Regulation T sets a limit on broker loans for
stocks, also known as margin. For the
past twenty-five years, the Fed has set the maximum margin loan at 50 percent
of the total investment. LTCM got around
this by building its equity positions without actually buying actual
securities. Rather, the fund entered
into derivative contracts that mimicked the behavior of stocks. If, for instance, LTCMM wanted to earn the
return on $100 million of CBS stock over a three-year period, it would strike a
“swap” contract with, say Swiss Bank.
LTCM would agree to make a fixed annual payment, calculated as an
interest rate on $100 million. And Swiss
Bank would agree to pay LTCM whatever profit would have been earned had LTCM
actually purchased the stock. This is
not new; Wall Street has been using equity swaps to get around Reg T for about
a decade.
Pg. 113: Long-Term’s plan was to return at the end of
1997, al profits on money invested during 1994, its first year, and to return
all money (principal and profits) invested after that date. They were determined to keep all the future
profits for themselves as this return of money invested excluded the partners
and employees and partially excluded some big strategic investors such as the
Bank of Taiwan. Jimmy Cayne, chief
executive of Bear Stearns, Long-Term’s clearing broker, got an exception,
too. The excluded were angry (but
lucky).
Pg. 123: Early in 1998, Long-Term began to short large
amounts of equity volatility. More than
any other, ‘equity vol’ was Long-Term’s signature trade, and it set the fund
ineluctably on the road to disaster.
Equity vol comes straight from the Black-Scholes model. It is based on the assumption that the
volatility of stocks is, over time, consistent.
The stock market, for instance, typically varies by about 15 percent to
20 percent a year. Now and then, the
market might be more volatile, but it will always revert to form—or so the
mathematicians at Long-Term believed. It
was guided by the unseen law of large numbers, which assured the world of a
normal distribution. This flowed from
the professors Mertonian view of markets as efficient machines that spit out
new prices with all the random logic of heat molecules dispersing through a
cloud. And when the models told them
that the markets were mispricing equity vol, they were willing to bet the firm
on it. However, there is no direct way
of making this bet. But there is an
indirect way. Remember that, according
to the Black-Scholes formula, the key element in pricing an option is the
expected volatility of the underlying asset.
As the asset gets jumpier, the price of the option rises. Therefore, if you knew the price of an
option, you could infer the level of volatility the market was expecting. The options market appeared to be anticipating
volatility in the stock market of roughly 20 percent. Long-Term viewed this as incorrect, because
actual volatility was only about 15 percent.
Thus, they figured that option prices would sooner or later fall. So Long-Term began to short options—specifically,
options on the Standard & Poor’s 500 stock index. Then on August 17, 1998 Russia declared a
debt moratorium. Long-Term, which had
calculated with such mathematical certainty that it was unlikely to lose more
than $35 million on any single day, dropped $553 million—15 percent of its
capital—on that one day.
