U.S. stock futures showed mixed signals as market participants await key earnings reports and economic data. The S&P 500 and Nasdaq futures edged lower amid a decline in semiconductor stocks, with investors focusing on the impact of these shifts. The Dow futures surged by 130 points, buoyed by stronger-than-expected earnings from UnitedHealth. Meanwhile, concerns over a cooling AI rally and the upcoming U.S. retail sales report are contributing to market jitters. As earnings season progresses, the market remains cautious amid persistent geopolitical tensions and inflation uncertainty.
