Stock futures took a downturn on Wednesday night, following two consecutive days of losses for the S&P 500 and Dow Jones Industrial Average. This trend was largely attributed to a 25% tariff imposed on certain semiconductors by President Donald Trump, which could potentially disrupt the technology supply chain. Tech stocks, including Microsoft, Meta, and Amazon, were among the biggest losers, with each shedding more than 2%. Oracle and Broadcom also took a hit, sliding 4% each, while Nvidia dipped 1.4%. The day's biggest laggards also included banks like Wells Fargo, Citigroup, and Bank of America, with Wells Fargo losing 4.6% after posting weaker-than-expected revenue for the fourth quarter. Despite these losses, portfolio consulting director Ayako Yoshioka from Wealth Enhancement Group remained optimistic, stating that the economy is relatively stable and that corporate earnings remain strong. However, geopolitical risks, such as tensions between the U.S. and Iran, and Trump's push for U.S. control of Greenland, continued to weigh on investor sentiment. Trump's recent attacks on Federal Reserve Chair Jerome Powell to lower interest rates have also raised concerns about the central bank's independence. Looking ahead, traders will be watching for earnings reports from Goldman Sachs, Morgan Stanley, and BlackRock, as well as weekly jobless claims, which could provide further insight into the market's trajectory.
