Investors got a blast of economic data, including a bigger-than-expected drop in retail sales and industrial output for August, which pointed at some weakness in the U.S. economy.
A separate report showed the number of Americans filing for unemployment benefits rose less than expected last week, pointing to a further tightening in labor market conditions.

Investors have been fretting over the possibility of a rate hike when the data-dependent Federal Reserve holds its policy-setting meeting next week, especially after contrasting comments from Fed officials in the past few days.

Apple was up 2.4 percent to $114.44, its fourth straight day of gains, after the company said the first batch of the iPhone 7 Plus sold out. The stock gave the biggest boost to all three indexes.
The energy index was the second biggest gainer, boosted by as oil prices rebound after two days of steep declines.
Aerie Pharmaceuticals soared more than 60 percent to $33.70 after its eye drug was successful in a trial.
Goodyear was the top percentage gainer on the S&P, rising 4.7 percent after it hiked its quarterly dividend and maintained financial targets for 2017.
