Alpha in Crisis: An Interview with William Harrington on Hedging and Macro Trading During the 2020 Market Crash

When markets lose direction amidst continuous fluctuations and panic becomes the most direct narrative, true macro traders are recalibrating their compasses. In William Harrington’s view, such epic volatility is not a disaster, but rather the most thorough test of trading philosophy and risk control systems, and the true source of “Alpha.”

Harrington argues that a crisis market is primarily a liquidity test, ruthlessly exposing vulnerable, homogeneous strategies. Traditional asset correlations often fail at this point, highlighting the true logic of macro hedging. His approach is not passive risk aversion, but proactive rebalancing. In his equity portfolio, he constructs “tail risk protection” through sophisticated options strategies. This is not simply buying put options, but hedging based on volatility surface analysis and specific risk factors, aiming to insure against known extreme risks at a reasonable cost. Simultaneously, he increases cross-market arbitrage efforts across government bonds, specific currencies, and even alternative assets, seeking out pricing distortions caused by panic selling.

He emphasized that in this environment, directional judgments often give way to relative value judgments between assets. Indiscriminate market declines present a golden window for identifying high-quality assets and those that have been unfairly punished. His trading system at this time focuses more on “deviation” analysis, identifying which asset prices have significantly deviated from their long-term fundamentals and macroeconomic logic, and positioning for subsequent mean reversion. This requires immense patience and discipline, as “catching a falling knife” is the greatest risk; one must wait for the market to show signs of liquidity depletion and a clearing signal.

Harrington summarizes his core strategy as “defense and counterattack.” Extreme risk control is the cornerstone of defense, ensuring survival in the storm; while a clear understanding of the macroeconomic landscape and a grasp of cross-asset linkages are the weapons for counterattack. He frankly admits that returns during such periods do not come from accurately predicting market bottoms, but from a systematic framework that can identify order from market disorder and extract value from extreme sentiment. Every crisis is a stress test and an opportunity to upgrade this framework, and true alpha is born within the commonly perceived fault lines of the market.
