Wall Street Sees Biggest Rotation Since 2020 Exposing AI Crowding Risks

Summary · why it matters

Wall Street staged a tentative recovery from one of the wildest weeks of the AI boom, belying a historic rotation beneath the surface that briefly exposed growing cracks in some of the grand assumptions underpinning global markets. The week brought a rout in technology shares, a fire sale by hedge fund Situational Awareness run by Leopold Aschenbrenner, and a surge in long-term borrowing costs, followed by a decisive snapback. Losses on leveraged AI bets triggered margin calls, forcing the fund to dump public equities until Ken Griffin's Citadel bought the bulk of its remaining public-equity portfolio. The selloff was accelerated by questions over AI investment payoffs and fresh doubts about new Fed Chair Kevin Warsh's commitment to curbing inflation, which pushed long-term Treasury yields higher. Quant factors swung by the most in at least four years, with momentum experiencing its biggest four-day plunge since the vaccine-fueled rotation of 2020 before posting its biggest one-day gain also since 2020, while laggards including value, quality, and low volatility surged. South Korea's Kospi surged a record 18.5% at one point on Friday, semiconductor shares snapped higher globally, and the S&P 500 eked out a 1% gain. The three sessions through Tuesday marked the sharpest degrossing by hedge funds since November 2022, according to Goldman Sachs's prime brokerage. JPMorgan strategists reckon the rotation has further to run, citing worsening sentiment and peaking money supply growth. The next threat lies in the bond market, where Warsh's press conference revived concerns about policy credibility and sticky inflation, steepening the Treasury yield curve with the gap between five- and 30-year yields widening by the most in a week since August 2025. Higher bond yields amplify concerns about AI investment by raising discount rates and the cost of capital, reducing the present value of long-duration growth expectations and making capital-intensive data-center projects more expensive to finance.
