Hedge Funds Hit Ctrl-Alt-Delete: $700B AI Rally Vanishes in 2.5 Hours

Roughly $700 billion in fresh US stock-market gains evaporated within hours on November 2, 2026, as an attempted technology rebound reversed and the S&P 500 closed down 0.5% despite rising as much as 1.1% in morning trading. The Nasdaq Composite fell 1.1%, extending the previous week’s AI-stock selloff, while the Nasdaq 100 had initially gained around 1.3% and the Dow climbed more than 1%. One market update described $700,000,000,000 being wiped from the US stock market in the last 2.5 hours. The day followed a late-October decline that erased more than $2 trillion from the Nasdaq-100.

Goldman Sachs data showed hedge funds net-sold global AI stocks for five consecutive sessions, reversing all their AI buying since the start of 2025. Morgan Stanley said hedge funds had reduced total stock bets by more than 8% since June, their biggest retreat since at least 2017. On their heaviest day, funds sold existing positions about 3.5 times faster than they opened new bearish bets. On October 22, Goldman’s basket of hedge-fund favorite stocks fell 4.2%, its worst day since 2011. “If last Thursday felt bad, today has been worse,” the bank’s prime brokerage desk said.

The October selloff was especially punishing for Samsung, SK Hynix, Micron and SanDisk, which together lost more than $700 billion in under two weeks. Steno Research’s recreation of Morgan Stanley data showed a -7.8% drop as of Oct. 27, 2026. Macro investor Jordi Visser estimated that leverage took 18 months to build and 75 days to unwind, describing one of the largest hedge-fund equity deleveraging events in the last 30 years without economic deleveraging. Corporate profits remained up about 20%, AI computing demand still outran supply, and SK Hynix forecast a memory shortage until 2030. Fundstrat’s Tom Lee suspected one forced seller drove the slide, while Goldman said the unwind looked closer to its start than its end. Funds’ AI holdings still ranked in the top 17% of the past three years.

Morning optimism came from oil prices dropping to $104 as possible US-Iran peace talks raised hopes of cheaper energy and easing inflation. At one point, the S&P 500 was up 1.0%, the Nasdaq 100 was up 1.3%, the Dow Jones was up 1.1%, WTI Crude was down 6.5%, Brent was down 7.0% and gold was up 2.0%, according to The Kobeissi Letter. The rally faded as Oracle plunged nearly 9% after announcing plans to raise $20 billion through stock and bond sales to fund AI expansion and Marvell lost almost 13%. CNBC host Jim Cramer had posted on X: “Here we go: biggest tech takeout,” referring to Marvell’s $115 billion acquisition of Lumentum. The timing prompted renewed attention to the Inverse Cramer ETF, which is designed to bet against his recommendations and lost 15% before closing in 2024.

White House economic adviser Kevin Hassett dismissed fears of an AI financing crisis. “There’s so much cash in the ecosystem that I think that people should be reassured,” Hassett said. Nearly 70% of S&P 500 companies finished higher, leaving weakness concentrated in major technology stocks. Investors were left facing Tuesday’s US midterm elections and Friday’s jobs report, with confidence in the AI trade already shaken.
