US stock futures are lower today as rising yields and concerns over major tech companies weigh heavily on investor sentiment. The S&P 500 futures have fallen, with the Nasdaq experiencing its worst month since April due to inflation and tariff pressures. Major indices, including the Dow Jones, continue to reflect mixed performance as the market approaches the close, with the Nasdaq hitting a more than one-week low and undergoing a significant sell-off driven by fears related to AI investments. Reports indicate losses in technology shares have predominantly influenced the global markets, leading to a broader decline. As investors await earnings reports from big tech companies, the overall market sentiment remains cautious amidst economic uncertainty.
