Investors may be taking a pause ahead of retail sales data due from the Commerce Department on Friday. Retailers offer an undefined look at the mood of the American consumer, who's spending drives about 70 percent of all U.S. economic activity.
Most economists expect a slight uptick in consumer spending for August.
On Wednesday, Commerce releases wholesale trade data for July. Economists believe steady sales gains have prompted businesses to restock more aggressively, which could drive economic growth.
