Wall Street is taking President Donald Trump’s latest threat on tariffs in stride, on the whole, and U.S. stocks are drifting higher on Monday. The S&P 500 was up 0.4% in early trading, coming off a losing weekbookended by worries about how potential tariffs could push up inflation and threaten the economy.

Wall Street's main indexes closed higher on Monday, lifted by Nvidia and other AI-related stocks, while steelmakers surged after U.S. President Donald Trump said he would impose additional tariffs on steel and aluminum imports.
