Recent market turbulence ignited by a rout in AI-related shares has caused a significant setback for hedge funds, particularly those employing systematic, or quantitative, strategies. These funds have surrendered approximately a quarter of their annual gains, with average returns plummeting from 14.4% in late June to 10.8% currently. This downturn highlights the vulnerability of "crowded" AI trades, where a large number of investors hold similar positions, leading to amplified losses during market corrections.
The sell-off was exacerbated by volatile swings in semiconductor stocks, a key segment of the AI industry. In certain markets, such as South Korea, elevated levels of retail investor leverage further intensified price fluctuations, making conditions especially challenging for trend-following strategies. Major players in the financial sector, including the Bank of England, the Bank of Japan, and the Bank for International Settlements, have previously warned about these risks, emphasizing how concentrated positioning and increased leverage can worsen market instability.
In response to the recent volatility, hedge funds have drastically reduced their leverage to the lowest levels in the past year, signaling a more defensive posture and a reassessment of market opportunities. Both systematic and fundamental equity hedge funds have been impacted, with the latter, which focus on stock-picking, recording average losses of 2.2%. Many fundamental managers have aggressively unwound their exposure to AI trades that had been significant drivers of performance earlier in the year, reflecting a rapid shift in market sentiment as volatility escalated.
