U.S. stocks experienced a significant boost on Monday, with the Dow Jones Industrial Average climbing 532 points, or 1.15%, as Apple shares hit a new all-time high. The S&P 500 and Nasdaq Composite also saw gains of 1.2% and 1.5%, respectively. Apple's stock surged over 4.3% to exceed $263, fueled by a Loop Capital upgrade and robust iPhone 17 sales surpassing those of the iPhone 16 in both the U.S. and China. Investor sentiment was further bolstered by comments from a Trump administration official indicating a potential end to the government shutdown, alongside optimism surrounding a possible U.S.-China trade agreement.
