Article excerpt

U.S. stock markets tumbled as investor anxiety over Big Tech companies' valuations and earnings prospects roiled Wall Street. The Nasdaq posted its largest single-day decline since early 2025, dragging down the broader market as traders reassessed whether mega-cap tech stocks had climbed too far. The selloff rippled across sectors, with major indices finishing sharply lower. Concerns about slowing growth, rising competition, and regulatory headwinds in the technology sector amplified the retreat, as investors rotated money into safer holdings.
