Nvidia Leads Tech Rally as Markets Overlook Geopolitical Tensions

U.S. stocks closed mostly higher on Tuesday, with the S&P 500 and Nasdaq 100 gaining due to strong performances by Nvidia and major tech stocks, despite early losses triggered by escalating Ukraine-Russia tensions. Nvidia surged 4% ahead of its earnings report, while Walmart's robust earnings also supported the market. The Dow Jones fell slightly, influenced by geopolitical concerns and weaker-than-expected U.S. housing data. Interest rates saw a decline as investors sought safe-haven assets amid the conflict, with European bond yields also dropping.
