What history says
Editorial commentary written by ALAN analysts. Figures cited below are analyst-authored context — they are not derived from the chart above and may reflect different windows or sources.
Swift policy response prevented systemic contagion
The Fed's rate cuts and coordinated bailout prevented LTCM's levered positions from cascading into broader failures. This established the precedent of the 'Fed put' for systemic risk.
Recovery was one of the fastest on record
From the October 1998 low, the S&P 500 rallied 35% over the next 6 months. Investors who panicked out missed one of the sharpest recoveries in history.
The lesson: leverage kills, diversification survives
LTCM's genius-level quants used 25:1 leverage. Their models were correct over time but the mark-to-market losses exceeded their capital. Leverage is the single greatest risk in investing.
For your portfolio
Audit your portfolio for leverage in every form — margin, leveraged funds, positions financed by loans — and size it so a six-week 22% market drop cannot force liquidation; LTCM was right on the trade and still failed because mark-to-market losses arrived before the payoff.
