Summary
Goldman Sachs prime brokerage data, first reported on Thursday, October 22, 2026, shows hedge funds have built short positions in stocks to a near five-year high. The positioning is bearish even as those same funds have been losing money. In October, short sales exceeded long purchases across global stocks by about five-to-one. Short leverage in Goldman's prime book reached the 99th percentile of its five-year history, indicating bearish exposure higher than in almost all of that period. Net leverage among fundamental long-short funds is near a three-year low while gross leverage has risen, meaning funds are adding risk on both sides of their books while leaning bearish overall. Goldman's Mark Wilson described net equity exposure as historically low amid swings in rates and energy prices, and said higher yields have pushed investors to rethink equity risk.
The losses have been significant. According to the report, global fundamental long-short funds lost 2.9% through October 15, with losses on every trading day in that stretch. Asia-focused stock pickers lost 6.8% in the first half of October. Such losses raise the risk of a short squeeze, in which rising prices force short sellers to buy back shares and push prices higher. Crowded short positions, however, do not indicate timing, and some shorts hedge long holdings and may remain open.
On October 22, the S&P 500 fell 93.74 points, or 1.21%, to 7,663.43, and the Nasdaq Composite dropped 2.6% to 26,008.86. The Dow added 11.89 points to 52,867.98 and the Russell 2000 gained 0.1%. Most stocks rose while megacap tech fell. The Philadelphia Semiconductor Index dropped over 6%, its largest daily percentage decline since June 23. Meta Platforms fell 6.98% to $648.85 after its third-quarter report, NVIDIA lost 4.40%, Amazon fell 4.57%, and Microsoft slipped 2.23%. The 10-year Treasury yield fell 19.3 basis points to 4.953%, its largest daily drop since March 10, 2023, and closed below 5% for the first time since September 23.
Fundstrat's Tom Lee said he believes the selloff is nearly over, citing a crowded short trade in tech and a Fed that may be shifting from hawkish to dovish. The Fed announces its decision on Wednesday, October 28, at 2:00 p.m. ET. Microsoft is expected to report around October 28 and Amazon around October 29, after the close, though neither company has confirmed its date. A yield rebound, weak megacap results, or a hawkish Fed would support the short thesis.
