Wall Street falls as inflation data sparks Fed fears
Wall Street declined as hotter-than-expected inflation data increased bets on further Fed rate hikes, hurting AI-related stocks like Oracle, CoreWeave, and Nebius. Dell and Hewlett Packard Enterprise also fell after a Barclays downgrade. Oil prices rose due to Houthi attacks on Saudi Aramco. The S&P 500, Nasdaq, and Dow Jones all dropped, with tech sectors leading losses. Bank of America and Morgan Stanley reported mixed earnings.
