Summary
Hedge funds are betting heavily against equities this month, with bearish wagers approaching a five-year high. Goldman Sachs reports that its prime brokerage clients have been selling stocks short at roughly five times the rate at which they have been buying them. Short exposure is now near the highest level seen in the past five years, and funds have also been scaling back their broader bullish bets, according to the source article on Bloomberg.com.

The positioning carries a risk of a sharp squeeze if markets rebound, as short sellers may be forced to cover into a rally. The shift comes as a well-established cycle of fear and frenzy around artificial intelligence moves lower, with AI-related selling deepening.

Macro conditions are adding to the pressure. US inflation, exacerbated by war-driven energy prices, is compounding concerns, while new signs that AI investments will not pay off in time have raised the prospect of a fresh selloff in chip and infrastructure stocks.
