Summary
Hedge funds endured a difficult stretch in October, with many funds posting their worst monthly performance since the covid-19 pandemic began, according to JPMorgan Chase, America's largest bank. A Bloomberg index tracking the industry's returns declined 1.7% for the month, reflecting broad losses across strategies.

The primary catalyst was a wobble in investor enthusiasm for artificial intelligence, which prompted a sell-off in technology stocks. Several other factors compounded the pressure, including the surprise re-election of Brazil's left-wing president, concerns over France's sovereign debt, and tumult in credit markets.

Losses were uneven across managers. The largest fund at Millennium, a major multi-strategy manager, fell 2.3%. The main fund of Arini Capital Management, a fast-growing credit firm, was down 19.7%, underscoring the risks concentrated in credit-focused strategies during the period.

The industry's struggles have continued into November, which has so far been bruising, featuring post-election market swings and the Jensen Huang affair. The Economist's analysis frames the episode as a set of lessons for allocators and managers as the sector navigates volatile markets.
