U.S. stock market futures on April 16, are experiencing declines, with the Dow Jones Industrial Average futures down 54 points, S&P 500 futures falling by 40 points, and Nasdaq futures dropping 270 points. The downturn is largely attributed to Nvidia's announcement of a $5.5 billion charge due to new U.S. export controls on its H20 AI chips to China. This development has also impacted other semiconductor stocks, including AMD and Micron Technology. Additionally, ASML reported weaker-than-expected orders, further weighing on the tech sector. Investors are closely watching Federal Reserve Chair Jerome Powell's upcoming speech and the release of retail sales data for further market direction.
