the U.S. stock market fell sharply in early trading on Thursday, with the Dow Jones Industrial Average plummeting more than 1500 points and the Nasdaq falling more than 1000 points. U.S. President Trump announced additional "equal tariffs" of 10% to 49% on almost all countries, which could trigger a global trade war and severely damage the already weak U.S. economy. The number of initial jobless claims in the U.S. unexpectedly dropped last week. Trump's tariffs and the OPEC+ production increase plan have caused oil prices to plummet. The Dow fell by 1543.14 points, or 3.65%, to 40682.18 points; the Nasdaq dropped 1004.16 points, or 5.71%, to 16596.89 points; and the S&P 500 index fell by 246.47 points, or 4.35%, to 5424.50 points.
