U.S. stock futures faced downward pressure on Wednesday, with S&P 500 and Nasdaq 100 futures both declining by approximately 0.4%, and Dow Jones futures falling nearly 80 points. This followed a mixed trading session the day before. Investor sentiment was cautious as anticipation built around President Donald Trump's forthcoming tariff announcement. Speculation indicates that Trump is considering implementing a blanket 20% tariff on the majority of imports. However, ambiguity remains regarding the extent and specific targets of these levies. The White House has commented that the tariffs would become effective immediately but emphasized that Trump is open to ongoing negotiations. Furthermore, the release of the ADP employment report early in the morning is expected to shed light on private-sector job growth for March. On the corporate landscape, major cap stocks displayed mixed outcomes. Apple, Microsoft, Nvidia, Meta, and Tesla saw declines of 0.4%, 0.4%, 0.8%, 0.4%, and 1.3%, respectively, whereas Amazon and Alphabet experienced slight upticks, increasing by 0.4% and 0.3%.
