NEW YORK — Big technology and internet companies came under heavy selling pressure again on Monday, leading to broad losses across the stock market. The Dow Jones Industrial Average briefly fell 500 points.
Apple, Microsoft and Amazon, the most valuable companies on the market, sustained some of the worst losses. Facebook, another longtime investor darling that has been falling out of favor, also fell sharply.
The jittery trading came after two days of gains last week as investors hoped that the U.S. and China were moving closer to settling their costly trade fight, which has been a major uncertainty for investors. Those hopes faded after the two countries clashed at a Pacific Rim summit over the weekend.
A steep loss for Boeing, a major exporter which would stand to suffer greatly in a protracted trade war, weighed heavily on the Dow. Boeing gave up 4.8 percent, but is still one of the best-performing stocks in the 30-stock index. Apple fell 3.5 percent on renewed worries that iPhone sales could slow, Microsoft lost 3.7 percent and Amazon gave back 4.1 percent.
High-dividend stocks like real estate companies and utilities, which investors favor when they are fearful of market turmoil, held up better than the rest of the market.
