Traders also looked to a speech from New York Federal Reserve President William Dudley.

Dudley said that future rate hikes depend on data and that rates are set to continue on gradual upward path. He added that overseas economies pose risk to the United States and there's little change in outlook since the Fed meeting.

Core inflation is quite stable despite lower energy, Dudley said, noting 2016 growth is to be slightly above 2 percent.

Consumer sentiment and business inventories are set to come out at 10:00 a.m.
