Key Takeaways
- • Hedge funds have pushed short exposure in global equities to near five-year highs, with short selling outpacing long buying by roughly five to one this month, according to Goldman Sachs prime brokerage data cited by Bloomberg.
- • Short leverage has reached the 99th percentile of its five-year range, while net leverage among fundamental long-short funds has fallen to near a three-year low.
- • Global fundamental long-short funds were down 2.5% in October as of Monday, cutting year-to-date gains to 10.1%; technology, media and telecom-focused managers have declined 7.4% month-to-date.
- • Goldman warns that crowded bearish positioning raises the risk of a short squeeze if equities rebound, though persistent inflation concerns and uncertainty over AI investment returns continue to weigh on sentiment.
Summary
The defensive positioning follows a sharp reversal in artificial intelligence-related stocks, driven by stronger-than-expected US inflation data and mounting concerns over returns on AI infrastructure spending. The Nasdaq 100 fell 5.5% last week, its steepest weekly decline since April 2025. Global fundamental long-short funds were down 2.5% in October as of Monday, reducing year-to-date gains to 10.1%, according to Goldman. Technology, media and telecommunications-focused managers have suffered the heaviest losses, declining 7.4% month-to-date.
Selling has been concentrated in technology. Global information technology stocks recorded their largest two-week net selling since Goldman began tracking the data more than a decade ago, in the period to 16 October. Net allocation to Goldman's global AI stock basket has fallen to the 38th percentile of its one-year range, and the long-short ratio has dropped to the sixth percentile, leaving managers heavily positioned against a potential technology rebound. Europe has been the only major region to record modest net buying this month, while net exposure to the Magnificent Seven technology stocks has reached a record high despite broader selling across the sector.
Goldman flagged the possibility of a short squeeze, noting that crowded bearish positioning leaves funds vulnerable to a sudden recovery in equity prices. Persistent inflation concerns and uncertainty over AI investment returns, however, continue to weigh on sentiment.
