US Hedge Funds Just Sold Every AI Stock They Bought Since 2025

Goldman Sachs data showed hedge funds spent five consecutive sessions in October 2026 selling artificial-intelligence shares, eliminating the net AI stock purchases they had made since January 2025. Morgan Stanley estimated that hedge funds reduced their overall equity wagers by over 8% from June, a withdrawal larger than any since at least 2017. Big tech stocks fell, erasing $2 trillion in market value, while memory-chip makers Samsung, SK Hynix, Micron and SanDisk lost more than $700 billion in under two weeks. On October 22, Goldman’s basket of hedge funds’ favorite stocks dropped 4.2%, its worst day since 2011.
