U.S. stocks experienced a modest uptick on Tuesday, slightly building on the record highs achieved in the previous session, primarily driven by gains in prominent tech stocks. Investors continued to evaluate the prospective returns from artificial intelligence firms and the outlook for interest rates. The Dow Jones Industrial Average advanced by 150 points, while the S&P 500 and Nasdaq 100 saw marginal increases above the break-even mark. Nvidia shares slightly declined after a 4% surge the previous day, following its announcement of a potential $100 billion investment in OpenAI. Meanwhile, Kenvue's stock surged over 5%, recovering previous losses as investors reassessed the effects of former President Trump's unsubstantiated criticism of Tylenol. Boeing's shares rose over 2%, propelling the Dow after Trump mentioned a significant $8 billion order from Uzbekistan Airways. On the macroeconomic side, market participants were anticipating comments from Federal Reserve Chair Jerome Powell, with a focus on the upcoming personal income and expenditure data scheduled for release on Friday.
