Understanding surprise events and the zero-sum game are critical to trend following trading success. Some core refreshers all traders should grasp regarding one of the great surprise events of our time:
If you think the Lowenstein interview is no longer relevant, as it is a few years old, you might be missing the point.
Why LTCM Still Matters
Long-Term Capital Management was founded in 1993 by John Meriwether with a team that included two future Nobel Prize laureates in economics, Robert Merton and Myron Scholes. The fund applied convergence trading strategies with extraordinary leverage across global fixed income markets, building a $100 billion balance sheet on a capital base of a fraction of that size. For four years it produced exceptional returns and was hailed as the most impressive hedge fund in history.
In August and September 1998, a Russian debt default triggered a global flight to quality that caused correlations across LTCM’s positions to move simultaneously against the fund. In five weeks, the Nobel Prize-winning geniuses went from running the world’s most admired hedge fund to requiring a Federal Reserve-organized bailout of $3.6 billion from the major Wall Street banks. The fund’s staggering leverage meant its failure threatened the stability of the global financial system.
The LTCM story is relevant to trend following for two structural reasons. First, LTCM ran a convergent strategy: betting that prices would return to historical relationships. The positions it took were long prices that had deviated below historical norms and short prices that had deviated above them. This is the opposite of trend following. Convergent strategies produce steady small gains until the event the model never anticipated arrives, at which point the losses are catastrophic. Trend following produces steady small losses during non-trending periods and occasional large gains when markets move strongly. The payoff profiles are structurally opposite. LTCM’s collapse is the convergent strategy’s failure documented in complete detail.
Second, the LTCM collapse created massive, sustained price movements across global markets as the fund’s forced liquidation reverberated through interconnected positions. Currencies moved. Bond spreads widened dramatically. Equity volatility spiked. These are exactly the conditions in which systematic trend following systems generate their largest returns. The event that destroyed LTCM created the opportunity environment that trend followers are positioned to exploit.
Lowenstein’s observation in the interview that the LTCM founder, after the collapse, was returning to the same strategy with $12-$18 of leverage per dollar of capital says everything about the limits of learning from catastrophic events. The models were wrong about the probability and magnitude of the surprise event. The response was to reduce leverage slightly and try again. Trend following’s response to surprise events is different by design: the system does not model the probability of the surprise. It responds to whatever the price does when the surprise arrives.
Frequently Asked Questions
What was Long-Term Capital Management and why did it fail?
LTCM was a hedge fund founded by John Meriwether with partners including Nobel laureates Robert Merton and Myron Scholes. It ran convergence trading strategies with extreme leverage, betting that prices would return to historical relationships. In 1998, a Russian debt default triggered simultaneous adverse moves across all its positions. In five weeks it lost most of its capital, requiring a $3.6 billion Federal Reserve-organized bailout. It seemed the geniuses couldn’t lose. Four years later, when a default in Russia set off a global storm that Long-Term’s models hadn’t anticipated, its supposedly safe portfolios imploded.
Why is the LTCM collapse relevant to trend following traders?
Because LTCM ran the structural opposite of trend following. Its convergent strategy produced steady gains until a surprise event produced catastrophic losses. Trend following’s divergent strategy produces steady small losses until a large market movement produces large gains. The event that destroyed LTCM, a sudden large correlated move across global markets, is exactly the type of event that produces trend following’s largest returns.
Why is the Lowenstein interview still relevant years after publication?
Because the structural lessons have not changed. The same convergent strategy logic that built and destroyed LTCM reappears in different forms in every market cycle. The same surprise events that models fail to anticipate continue to occur with regularity. The same zero-sum arithmetic means someone profits from every LTCM-type collapse. Understanding the structural difference between convergent and divergent strategies, and why surprise events punish the former and reward the latter, is as relevant today as it was in 1998.
