Summary
Global hedge funds suffered steep losses during the week to October 15, 2026, according to a Goldman Sachs prime brokerage note cited by Reuters. The losses were driven by the sharp unwinding of a broad set of AI-related positions, with Asia-focused funds hit hardest. Global fundamental long-short funds, or stock pickers, lost money every single day that week, with weekly losses of 2.9%. Despite this, they remain up 14.3% year to date.
The selloff intensified on Wednesday, when hedge funds across strategies retreated sharply. Global stock pickers lost 0.9% that day, Asia-focused managers fell 2.6%, and tech-focused funds declined 2.0%. Global systematic long-short managers and multi-strategy funds each fell roughly 1%. Goldman Sachs noted that all three broad strategies had never fallen more than 80 basis points on the same day from the COVID period through the end of 2025, and that this threshold has now been breached three times this year: on February 4, July 28, and October 15.
Market pressure centered on semiconductors and the AI supply chain. Hotter-than-expected US inflation data increased expectations of further rate hikes, which fed investor doubts about whether heavy AI spending can generate returns soon, given that elevated inflation keeps borrowing costs high. South Korea's benchmark KOSPI tumbled 8% to close at a six-month low on Thursday, and Taiwan stocks lost more than 3%. Asia-focused stock pickers have lost 6.8% in the first half of October, erasing more than half of the gains accumulated since their late-June peak, according to Goldman Sachs.
