Markit Economics will release its reading on the US services sector at 9:45 a.m. ET.
Economists estimate that the flash services PMI for December was 55.9, versus 56.1 prior.
The previous report for November showed that employment, new business, and output all rose at a faster pace in November.
The new report would give us a better look at how the services sector, which makes an outsized contribution to the economy compared to manufacturing, fared in the 4th quarter.
