U.S. Stock markets closed lower on Friday, February 27, 2026, ending a volatile month marked by concerns over artificial intelligence valuations and global trade policy. The Dow Jones Industrial Average fell by more than 500 points, closing down 1%, while the Nasdaq Composite declined 0.8% and the S&P 500 dropped 0.4%, according to preliminary market data.
The declines followed a week of fluctuating investor sentiment, initially buoyed by President Donald Trump’s State of the Union address which confirmed a 10% global tariff. Despite the tariff announcement, technology stocks, particularly those linked to artificial intelligence, had experienced a rally earlier in the week. The Dow Jones Industrial Average had previously reached 49,369.65 on Wednesday, February 25, 2026, a gain of 0.40%, while the S&P 500 climbed to 6,927.93, up 0.55%, and the Nasdaq Composite surged to 23,044.10, a 0.79% increase.
Nvidia’s upcoming earnings report continued to be a significant driver of market activity. Volume in Nvidia alone exceeded 175 million shares on Wednesday, indicating substantial institutional investment ahead of the release. Oracle also saw gains, jumping over 2% following an upgrade from Oppenheimer, who cited a favorable risk-reward profile after a 25% year-to-date selloff. Tesla’s stock price rose 2.39% to $409.38, benefiting from a broader rebound among the “Magnificent Seven” stocks and speculation surrounding a potential merger with SpaceX and xAI.
Software companies also experienced a boost as Anthropic’s new “Claude Cowork” integrations with Google Drive and Microsoft Excel alleviated concerns that AI would replace existing software-as-a-service (SaaS) tools. This eased fears of software disruption, contributing to the overall positive sentiment in the tech sector. Market breadth remained constructive despite ongoing geopolitical risks related to Iran and global tariff tensions.
On Wednesday, February 25, 2026, the Dow Jones Industrial Average increased 224 points, or 0.5%, the S&P 500 added 0.5%, and the Nasdaq Composite traded up about 0.7% during morning trading. However, this momentum did not sustain through the end of the week, culminating in Friday’s declines.
