U.S. stock futures tumble indicating another plummet on Wall Street

(Reuters) -U.S. stock futures opened sharply lower late on Sunday, suggesting a continuation of the two-day selloff that wiped trillions from equity values after the Trump administration's tariffs announcement last week. Investors had been anticipating another week of turbulence as global trading partners react to the harsher-than-expected tariffs. U.S. S&P 500 E-minis stock futures were last down 4%.
