(Reuters) - Wall Street stocks ended sharply lower on Wednesday, dragged down by losses in Nvidia and Tesla as investors awaited information about long-promised U.S. tariffs on automotive imports.
U.S. President Donald Trump was set to announce plans for car-industry tariffs at a press conference on Wednesday, widening the global trade war he kicked off this year. Auto industry experts expect the move to drive up prices and stymie production. For weeks, Trump has promised to announce a swath of reciprocal tariffs on April 2.
Shares of Tesla dropped 5.6% and General Motors lost 3.1%, with investors uncertain about the scale of tariffs, retaliatory measures from trading partners and potential ripple effects on the global economy and businesses.
"Markets hate the tariff uncertainty, especially when it pertains to autos. Autos are ground zero for the negative economic impacts of tariffs," said Jamie Cox, managing partner at Harris Financial Group.
