CITIGROUP strategists led by David Chew say US tech stocks face further downside as positioning remains elevated: the Nasdaq-100's pullback this month was not matched by a reduction in exposure, leaving long positions still materially larger than shorts and roughly 80% of longs currently underwater. The team warns risk is skewed toward losing long positions, which could amplify downward pressure. AI valuation doubts have triggered tech selling, with large-cap US techs leading and the Nasdaq-100 down about 2% this month and on track for its worst June since 2022. Goldman Sachs prime-brokerage data show hedge funds sharply cut US tech exposure last week, with absolute and relative net selling at the highest levels in over a decade. CITIGROUP also flags bearish flows in the Nasdaq-100 and S&P 500 and a rotation into the Russell 2000.
