Nasdaq 100 Tumbles Over 3%, Marvell Crashes 12%: Stock Market Today

U.S. stocks declined sharply on Tuesday as investors rotated out of high-flying chip and AI stocks. The Nasdaq 100 fell 3.3%, the S&P 500 dropped 1.6%, and the Russell 2000 fell 1.3%. Oil prices collapsed 6% following a halt in Israel-Iran strikes. Markets are now pricing in a potential Fed rate hike by October rather than cuts, pressuring richly valued tech stocks. Semiconductor and optical companies led losses, while defensive and financial sectors provided some cushion.
