Health care and energy companies led U.S. stocks lower. The S&P 500, which has risen for the past three weeks, fell 0.4 percent to 2,774.88. The Dow Jones Industrial Average also lost 0.4 percent, to 25,850.63. The Nasdaq composite declined 0.4 percent to 7,459.71 while the Russell 2000 index of smaller companies gave up 0.4 percent to 1,575.55.
A hodge-podge of recent economic data is fueling concerns over risks to global growth. The U.S. Labor Department said fewer workers applied for unemployment benefits last week than economists expected, an encouraging sign. But investors are cautious about business conditions going forward as signs of weakness in the global economy emerge. The long-running, costly trade dispute between the U.S. and China has also clouded the outlook.
The world's two biggest economies are locked in a trade war spurred by U.S. contentions that China uses predatory tactics in a quest to overtake U.S. technological dominance, including pressuring American companies to hand over trade secrets and in some cases stealing them outright.
The Trump administration has warned it will increase its import taxes on $200 billion in Chinese goods from 10 percent to 25 percent if the two sides haven't reached a resolution by March 2. But Trump in recent days has signaled a willingness to extend the deadline if negotiators are making progress.
"The trade talks do appear to have made some progress, however, but a run of weak data from Japan, Europe and the U.S. yesterday took the wind out of the equity market sails," said Jeffrey Halley, senior market analyst at OANDA.
