  • • Crowded trades are unwinding quickly after the month, with AI-related positions among the first to be humbled, followed by macro shocks and credit scares.

Summary
Hedge funds were hit hard in October, according to Bloomberg, as a broad selloff in technology stocks coincided with a surprise election result in Brazil and violent protests in France. The combination left many of the world's most closely watched money managers nursing losses.

The pain unfolded in stages. Positions tied to artificial intelligence, which had been crowded among managers, were the first to falter. Macro shocks followed, and credit scares came next, leaving managers with few places to hide. By the end of the month, the source reports, the damage had spread across the industry.

Bloomberg's account centers on the speed of the reversal. Crowded trades, where many funds hold the same positions, are now unwinding quickly, a dynamic that tends to amplify losses when managers rush for the exit at the same time. The source does not provide fund-level performance figures or AUM data for the period.
