U.S. stocks are lower on Monday after a three-day holiday break as investors keep an eye out for more trade-related developments.

US stock futures fell as President Trump threatened stiff tariffs on imports from more than a dozen countries and delayed the return of sweeping April levies.

Stocks on Wall Street fell sharply on Monday, led by losses across major indices, including the Dow Jones Industrial Average, S&P 500, and Nasdaq. The S&P 500 shed 0.8%, its worst single-day drop since mid-June, while the Dow and Nasdaq both declined 0.9%. Despite the setback, all three indices remained close to their recent record highs.
