U.S. stock futures showed mixed movements on Wednesday as investors analyzed major tech earnings and prepared for the Federal Reserve's latest monetary policy decision. Dow futures fell by 0.4%, while S&P 500 and Nasdaq 100 futures rose by 0.2% and 0.7%, respectively. In extended trading, Microsoft dropped by 2.7% as disappointing cloud technology results overshadowed better-than-expected profit and revenue figures. Meanwhile, AMD surged by 7.6% due to strong quarterly results, boosting Nvidia's AI-related prices by 5%. During regular trading on Tuesday, the Dow rose by 0.5%, while the S&P 500 and Nasdaq Composite fell by 0.5% and 1.28%, respectively. These movements occurred as investors continued to move away from tech companies amid doubts about the sustainability of the AI rally, shifting their focus to more traditional sectors of the U.S. economy. Investors now await further earnings reports and economic data on Wednesday, as well as the Fed's policy announcement.
