The Standard & Poor’s 500 climbed 0.7%, coming off a losing week that was bookended by worries about how potential tariffs could push up inflation and threaten the economy. The Dow Jones industrial average added 167 points, or 0.4%, and the Nasdaq composite rallied 1% as Nvidia and other Big Tech stocks led the way.

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.

"If it escalates into bilateral tariffs, we estimate an 8% hit to EPS assuming unitary elasticity," Bank of America analysts said.
