Summary
Hedge funds lost an estimated 1.4% in October 2026, according to Hedge Fund Research (HFR), as sharp declines in technology and AI-related equities weighed on growth exposures and managers positioned for policy changes following the US midterm elections. About 60% of hedge funds lost money during the month. Despite the October decline, the HFRI Fund Weighted Composite Index has risen 5.42% since the start of January.
Equity strategies drove the bulk of the losses. The HFRI Equity Hedge (Total) Index fell 2.4%, led by the Fundamental Growth Index, down 5.6%, and the Technology Index, down 4.8%. The declines tracked a steep selloff in US technology stocks, with the Nasdaq Composite falling 5.3% over the month, its weakest monthly performance since March 2025. The Dow and the Russell 2000 finished in positive territory. HFR said Intel, Alphabet, Meta Platforms and Nvidia were among the firms with the heaviest falls.
Other strategies were mixed. The HFRI Event-Driven (Total) Index slipped 0.2% as managers positioned for increased IPO activity in November. Activist strategies gained 3.6% and merger arbitrage added 0.1%, while credit arbitrage lost 2.7% and distressed/restructuring fell 1.8%. The HFRI Macro (Total) Index declined 1%, with discretionary thematic funds down 3.2% and commodity funds off 1.9%; systematic trend-followers were roughly flat at -0.1%. The HFRI Relative Value (Total) Index gained 0.2%, supported by sovereign fixed income (up 5.3%), yield alternatives (up 4.6%) and asset-backed strategies (up 2.1%). HFR's liquid alternative indices also declined, with the HFRX Global Hedge Fund Index down 1.2% and the HFRX Absolute Return Index down 0.4%.
Dispersion across managers widened. The top decile of the composite's constituents averaged a 7.7% gain, while the bottom decile lost 13.2%, a 20.9% spread compared with 14.6% in September. Over the trailing 12 months to October, the gap between top and bottom deciles reached 61.2%.
HFR said managers spent October positioning for US policy changes following the midterm elections, which shifted control of Congress to the Democrats. Heinz said the outcome "guarantees that volatility will remain elevated over the intermediate term." He cited AI regulation, data centres, tariffs, taxes, interest rates and the Iran conflict as factors that will drive market performance. The October loss contrasts with a year earlier, when hedge funds extended their gains.
