S&P 500 falls even with most stocks rising as traders dump AI names

The nascent pullback across high-flying, AI-linked names picked up steam on Tuesday, sending major indexes down even as most stocks went up.

The S&P 500 fell 0.6% despite having far more gainers than losers, the Nasdaq 100 tumbled 1.4%, and the Russell 2000 gave back 0.8%.

The iShares MSCI USA Momentum Factor ETF had its worst day since the opening session of Q3, with Palantir leading S&P decliners. The AI darling fell 9.3% to match its longest losing streak since April 2024.

As you’d expect given the tape, with indexes down despite most stocks rising, the pain at the S&P 500 sector ETF level was concentrated in tech — communication services and consumer discretionary were the only other two sectors to fall on Tuesday. Morgan Stanley’s basket of AI tech beneficiaries suffered its biggest one-day drop since April 10, falling 4.1%.

Gains on the day were led by Intel, which rose 6.9% after the company reported that Japanese tech giant SoftBank Group was buying a $2 billion stake in the US chipmaker. Elsewhere...
