Key Takeaways
- • An anonymous hedge fund manager warns against trading major currency pairs (dollar-sterling, dollar-euro, dollar-yen), citing lack of edge and historical examples of sophisticated investors suffering catastrophic losses in FX markets.
- • The manager emphasizes that currency weakness in the short term should not be extrapolated into permanent trends; currency processes are "mean-reverting" over the long term, despite short-term volatility that hedge funds exploit.
- • Julian Robertson's late-1990s bet against the yen—which appeared fundamentally sound given Japan's deflation and banking crisis—resulted in massive losses when the yen strengthened 10-15% during the 1998 financial crisis, illustrating the hazards of directional currency bets.
- • The interview, conducted in October 2007 during the subprime mortgage collapse, captures a hedge fund manager's perspective on market structure, risk management, and the distinction between long-term structural analysis and short-term trading reality.
Summary
In October 2007, at the height of the subprime mortgage crisis, n+1 editor Keith Gessen interviewed an anonymous managing partner at a major New York hedge fund to explore perspectives on market dysfunction and investment strategy. The conversation, which later expanded into the 2010 book *Diary of a Very Bad Year: Confessions of an Anonymous Hedge Fund Manager*, reveals sophisticated thinking about currency markets and the pitfalls of directional macro bets.
When asked whether America had become a "Third World country" amid the weak dollar, the manager responded with measured skepticism about long-term currency forecasting. While acknowledging short-term dollar weakness, he argued that currency movements tend toward mean reversion over extended periods and that extrapolating current weakness into permanent decline is a common investor error. However, he clarified that his own hedge fund operates on shorter time horizons where such long-term patterns matter less.
The manager was notably candid about the fund's strategic limitations, emphasizing that despite its expertise in other markets, it deliberately avoids trading major currency crosses—dollar-sterling, dollar-euro, and dollar-yen—because it lacks a genuine edge in those markets. This restraint reflects deep respect for the difficulty of FX trading, illustrated through a vivid cautionary tale: Julian Robertson, a legendary investor, suffered devastating losses in the late 1990s betting heavily against the yen while going long the dollar. Robertson's thesis appeared sound—Japan faced severe deflation, a weakened banking system, and structural economic malaise—yet during the 1998 financial crisis, the yen unexpectedly strengthened by 10-15%, obliterating his position. The manager used the colloquial phrase "carried out on a board," describing how Robertson and other sophisticated investors were effectively "dead" as traders after such losses.
This interview captures a candid moment in hedge fund thinking during the crisis period, emphasizing disciplined capital allocation, respect for market complexity, and the distinction between sound fundamental analysis and successful short-term trading execution.
