The Labor Department normally would release weekly jobless claims at 8:30 a.m. ET, but the numbers are unlikely to come out today because of the government shutdown. Factory orders from the Commerce Department at 10 a.m. ET and natural-gas inventories from the Energy Department at 10:30 a.m. ET will probably be skipped as well.
Economists were looking for claims to rise to 315,000 from 305,000 in the previous week. Factory orders, which cover the month of August, were expected to increase 0.3 percent after a 2.4 percent drop in July.
Constellation Brands is the main company reporting earnings, with its release scheduled for before the opening bell.
