Improving international sales helped McDonald’s overcome some weakness at home in the fourth quarter, but the company said it expects U.S. sales to pick up later this year.

McDonald’s said its sales are continuing to recover from an E. coli outbreak last fall tied to its Quarter Pounder hamburgers. The Chicago burger giant said it’s also struggling to get low-income consumers back into its stores despite expanding discounts.

McDonald’s U.S. same-store sales, or sales at locations open at least a year, fell 1.4% in the fourth quarter.

U.S. stocks rose Monday as Wall Street took President Donald Trump’s latest threat on tariffs in stride.

The S&P 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.

The bond market also remained relatively firm, with Treasury yields making only modest moves after Trump said over the weekend that he would announce 25% tariffs on all steel and aluminum imports, as well as other import duties later in the week.

The price of gold, which often rises when investors are feeling nervous, climbed again Monday to top $2,930 per ounce and set another record.

Stocks of U.S. steel and aluminum producers jumped Monday, banking on expectations tariffs could help their profits.
