what happened with stock market today

Today, October 11, 2025, the U.S. stock market experienced a notable decline driven primarily by renewed trade tensions between the U.S. and China. Following President Trump's announcement of imposing a 100% tariff on Chinese goods and the implementation of export controls on critical software starting November 1, major indices fell significantly. The Dow Jones U.S. Total Stock Market Index dropped approximately 2.76%, losing around 1837 points, reflecting widespread investor concern. This follows a recent downturn after last Friday's market saw the Dow fall nearly 900 points, the S&P 500 decline by over 2.7%, and the Nasdaq plunge around 3.6%, as tech and semiconductor stocks were hit hardest amid fears of escalating trade conflicts and economic growth disruption. Details from recent sessions also highlighted that the U.S. government shutdown contributed to market uncertainty, while Chinese retaliatory measures such as export restrictions and port fees added to the negative sentiment. The market's reaction represents the sharpest single-day losses since April, with all major indices marking a disappointing week after weeks of gains near record highs. Overall, Trump's tariff threats and escalating US-China trade tensions dominated market movement and investor sentiment today, causing marked sell-offs and volatility across sectors.
