Hedge Funds Struggle Amid AI-Driven Tech Selloff

- The selloff was particularly damaging due to hedge funds' crowded long positions in popular technology stocks; as funds rushed to exit these concentrated trades, it triggered a momentum-driven selloff. - During one of the worst days, hedge fund strategies focused on technology, telecoms, and media fell by as much as 2.8%. For context, many funds aim for 1-2% positive returns per month to achieve double-digit annual returns after fees. - The S&P 500 software and services index has fallen nearly 18% this year, wiping out over $1.2 trillion in market value. This has led to global long/short equity funds losing approximately 2% in "alpha returns," which are profits derived from a trading edge rather than general market movements. - The recent market volatility was reportedly initiated by the release of a new legal AI tool from Anthropic's Claude, which sparked investor concerns about the disruption of existing software and business models. - In response to the selloff, hedge funds have been net sellers of U.S. equities at the fastest rate since March 2025. They are actively shorting software stocks while purchasing shares of companies that produce microchips and other electronic components related to AI technology. - The notional value of short selling on individual stocks recently reached its highest level since Goldman Sachs began tracking the data in 2016, with short sales outpacing long purchases by about two-to-one in early February. - This market event has not been a broad market retreat but more of a rotation. While software and other growth stocks have been sold off, capital has flowed into semiconductors, industrials, utilities, and companies associated with AI infrastructure. - Some multi-strategy funds, despite having their worst day since April 2025 with equity books down 1.9%, have shown resilience and remain up 3.9% for the year to date.
