NEW YORK—U.S. stocks plunged Wednesday as investors, fearful that rising interest rates and trade tensions could hurt company profits, ramped up their selling of high-flying technology and internet stocks. The Dow Jones Industrial Average fell 831 points, its worst loss in eight months.
The losses were widespread, and stocks that have been the biggest winners on the market suffered steep declines. Apple and Amazon, the two most valuable companies in the S&P 500, each had their worst day in two and a half years.
