What had been a steady pullback from the US stock market accelerated sharply Monday as investors retreated from virtually every type of risk and economic fear raced across Wall Street.

Major U.S. stock indexes sank on Monday after U.S. President Donald Trump declined to predict whether his tariff policies could lead to a recession, roiling investor sentiment. The Nasdaq Composite sank more than 4% after confirming last week that its retreat from December's record high was a correction.
