The Dow Jones Industrial Average edged down 0.1%, while the Nasdaq composite inched up less than 0.1%. Later this week will come profit reports from Walmart and other big U.S. retailers, which could show how households are navigating a slowing job market and worries about tariffs. The week's highlight will likely arrive Friday, when the Federal Reserve's chair will give a speech that Wall Street hopes will hint at cuts to interest rates coming soon.
