(AP) -- Fresh market jitters over the possibility of an escalation in the costly trade war between the U.S. and China pulled stocks broadly lower on Wall Street Monday.
The decline, which gradually lost momentum after an initial steep slump, came a day after President Donald Trump threatened to raise tariffs on goods imported from China. Trump complained that the trade talks between the two countries are moving too slowly.
Investors have been expecting Washington and Beijing to resolve their damaging trade dispute after both sides sent signals in recent months that talks were progressing. Hopes for an accord between the world's two largest economies contributed to the big run-up in stock prices in the U.S. and China so far this year. The S&P 500 and Nasdaq hit all-time highs last week.
U.S. companies with heavy business interests in China bore the brunt of the selling Monday, particularly technology and industrial companies. Banks also fell sharply. Health care stocks rose.
Still, the wave of selling eased as the day went on, a sign that investors' trade deal hopes haven't dimmed entirely. Representatives from both sides were set to meet this week in Washington.
"You've seen that the sell-off has been so far contained and part of that is the perception that the president has done this before," said Marina Severinovsky, investment strategist at Schroders.
The S&P 500 dropped 13.17 points, or 0.4%, to 2,932.47. At one point, the benchmark index had been down 1.6%.
The Dow Jones Industrial Average fell 66.47 points, or 0.3%, to 26,438.48. It had been down as much as 471 points in the first few minutes of trading.
The Nasdaq slid 40.71 points, or 0.5%, to 8,123.29. The Russell 2000 index of small company stocks bucked the trend, adding 0.95 points, or 0.1%, to 1,614.98.
Major indexes in Europe and Asia finished lower.
The U.S. and China have raised tariffs on tens of billions of dollars of each other's goods in their dispute over U.S. complaints about Chinese technology ambitions.
Trump turned up the heat Sunday when he threatened to raise tariffs on imports from China to 25% from 10%. He also said he would impose tariffs on another $325 billion in imports from China, covering everything the country ships annually to the United States.
Tariffs currently in place have already raised costs on goods for companies and consumers, and disrupted trade in goods from soybeans to medical equipment.
Even with the new threat of escalation, another round of trade talks between the two countries are scheduled for later this week.
Severinovsky expects Washington and Beijing will strike a deal sometime in the next two months, noting that much of the president's latest comments on the negotiations comes down to posturing.
"We've become much more inured to this sort of drama just because he does tweet every day," she said.
Many sectors of the market posted declines Monday, including technology, industrial and materials companies, retailers and banks.
Qualcomm, which gets 64.7% of its revenue from China, according to the data provider FactSet, fell 1.2%. Broadcom slid 1.3% and Apple dropped 1.5%.
Chipmakers Micron Technology and Advance Micro Devices each dropped 2.8%.
Industrial behemoth Caterpillar lost 1.7%, while Deere & Co. gave up 4%.
Wynn Resorts, with a host of casinos and hotels in Macau, gets about 75% of its revenue from China. Its stock tumbled 4.1%.
Investors fled to safer holdings. Bond prices rose, sending the 10-year Treasury yield down to 2.50% from 2.53% late Friday.
Chinese indexes plunged. The Shanghai Composite index closed 5.6% lower and Hong Kong's Hang Seng index sank 2.9%. European indexes fell broadly.
Shares of Chinese companies that trade in the U.S. also fell. J.D.com slid 4.5%, while internet search company Baidu dropped 1.5%.
Investors have been digesting mixed reports about the U.S.-China trade talks for months and have largely discounted concerns about a failure in negotiations. The broader market has been posting gains all year on encouraging economic growth and solid corporate earnings results.
Elsewhere in the market, Boeing fell 1.3% after it disclosed that it did not warn airlines about a faulty safety alert until after one of its planes crashed.
The sensors malfunctioned during an October flight in Indonesia and another in March in Ethiopia, causing software on the plane to push the nose down. Pilots were unable to regain control of either plane and both crashed, killing 346 people.
Energy futures closed mostly lower. Benchmark U.S. crude rose 0.5% to settle at $62.25 per barrel. Brent crude, the international standard, gained 0.6% to close at $71.24.
