U.S. stock futures traded slightly lower on Wednesday evening as investors assessed a mixed round of earnings from major technology companies and absorbed the Federal Reserve’s latest policy update, while remaining cautious ahead of more high-profile corporate results. S&P 500 futures slipped about 0.2% to 6,994 points, Nasdaq 100 futures were little changed at around 26,160 points, and Dow Jones futures declined roughly 0.3% to near 49,019 points, reflecting a subdued risk appetite in late trading. After the bell, market reactions were driven largely by results from heavyweight technology firms, which set the tone for stock futures. Strong advertising demand and improving returns from artificial intelligence investments helped reassure investors about growth prospects in the digital advertising space. In contrast, Microsoft weighed on sentiment after its shares dropped about 7% following the release of its fiscal second-quarter results.
