Key Takeaways
- • Hedge funds posted their worst monthly performance relative to the S&P 500 in July in more than 20 years, driven by a sharp reversal in artificial intelligence stocks that forced widespread position exits across the sector.
- • Goldman Sachs data reveals hedge funds' basket of most widely held stocks suffered its worst one-month relative performance in over two decades of data, with portfolio turnover having reached its highest level since 2021 during the preceding quarter.
- • The AI trade unwind triggered one of the most pronounced de-grossing episodes in the past decade, with managers cutting exposure to semiconductor companies and mega-cap technology names that had been primary portfolio holdings during the AI rally.
- • Technology stocks represented 14 of 20 "Rising Stars" (companies with largest increases in hedge fund ownership) during Q2, but subsequent losses forced broad diversification away from crowded AI positions as gross leverage, net leverage, and overall AI exposure contracted from peak levels.
Summary
Hedge funds experienced a historic setback in July as aggressive positioning in artificial intelligence stocks rapidly unwound, resulting in the sector's sharpest monthly underperformance against the S&P 500 in more than two decades. According to Goldman Sachs data cited by CNBC, the bank's basket of stocks most widely held by hedge funds recorded its worst one-month relative performance in over 20 years of available data, marking a dramatic reversal from earlier gains driven by the AI investment theme.
The magnitude of the unwind reflects the concentrated nature of hedge fund positioning during the prior quarter. Entering the second quarter, managers had embraced the AI trade aggressively, with portfolio turnover reaching its highest level since 2021. This concentrated bet initially proved profitable, as AI-linked stocks drove strong hedge fund returns during Q2 and pushed crowding in widely held positions to record levels. Technology stocks dominated the quarter's performance, accounting for 14 of the 20 "Rising Stars"—companies that recorded the largest increases in hedge fund ownership during that period.
The subsequent July reversal forced a comprehensive reassessment of these positions. Managers began reducing exposure to the semiconductor stocks and mega-cap technology companies that had been among their most favored investments just weeks prior. This de-grossing episode represents one of the most pronounced episodes of hedge fund position-cutting in the past decade, spanning across a range of AI-related holdings. Goldman Sachs reported that hedge funds have reduced gross leverage, net leverage, and overall artificial intelligence exposure from the elevated levels reached during the second quarter, signaling a broader shift toward portfolio diversification as the AI trade lost momentum.
The July setback underscores the risks inherent in crowded positioning, particularly when sector-specific momentum reverses sharply. The rapid shift from aggressive accumulation to broad-based de-risking illustrates how quickly consensus trades can unwind when underlying support erodes, leaving managers forced to execute exits simultaneously across overlapping positions.
