LTCM

Algorithm

Long-Term Capital Management’s (LTCM) core resided in relative value arbitrage, employing sophisticated statistical models to identify and exploit perceived mispricings across fixed income and, later, derivative markets. These algorithms sought to profit from mean reversion, assuming deviations from historical relationships would correct, generating risk-adjusted returns. The firm’s models, while initially successful, relied heavily on historical correlations remaining stable, a critical assumption challenged by the 1998 Russian financial crisis. Consequently, the algorithmic approach, lacking robust stress testing for systemic events, amplified losses when market dynamics shifted unexpectedly.
