U.S. equity markets ended the week of November 7, 2025, with sharp declines across major indices as skepticism over elevated valuations in the artificial intelligence sector drove a pronounced tech sell-off. The S&P 500 fell about 1.6%, the Dow Jones declined 1.2%, and the Nasdaq Composite dropped 3%, marking its worst weekly performance since April. These losses reflected concentrated risk in tech and AI-linked stocks, including significant declines in Alphabet, Tesla, and leading chipmakers, which outweighed gains in select consumer and travel names.
Investor sentiment turned cautious as macro factors—particularly the prolonged U.S. government shutdown and deteriorating consumer confidence—added to uncertainty. Global markets were also impacted by weaker economic data from Europe and China, volatile currency moves, and concerns about the pace of central bank rate adjustments. As the week ended, the defensive posture among market participants reflected both sector concentration risks and persistent macroeconomic headwinds.
