Here comes ISM services ...
Markit's services purchasing manager's index is due first at 9:45 a.m. ET, and is forecast at 54. ISM's non-manufacturing PMI is forecast at 56.5, unchanged from January.
Readings above 50 would show that the largest contributor to gross domestic product remains in expansion.
"Activity in the services sector has been remarkably steady of late, hovering just above the 56-level for three consecutive months," said Wells Fargo's Sam Bullard in a preview.
"Price pressures mounted further last month, with the prices paid index rising at the fastest rate since the spring of 2014. A weighted average of both ISMs shows economic activity has strengthened noticeably since the middle of 2016."
The rise in both services and manufacturing indicators suggests that business investment may be on the rise again after a slowdown.
