U.S. stock futures declined early Wednesday, driven by a notable drop in Nvidia shares following after-hours trading. The chipmaker experienced a roughly 6% decrease after announcing a $5.5 billion quarterly charge related to export restrictions on its H20 graphics processing units bound for China and other nations. Investors are also preparing for a series of corporate earnings reports, expected later in the day, from companies including Abbott, U.S. Bancorp, and Travelers. Additionally, March retail sales data is anticipated, offering insights into the impact of escalating tariff concerns on consumer behavior. On Tuesday, major indices ended lower amidst ongoing trade uncertainty, with the Dow decreasing by 0.38%, the S&P 500 slipping 0.17%, and the Nasdaq Composite falling by 0.05%. Market participants continue to concentrate on the rising tensions between the U.S. and China, as the Commerce Department has initiated an investigation into semiconductor and pharmaceutical imports, potentially leading to further tariffs.
