The Institute for Supply Management released its non-manufacturing purchasing managers' index for the U.S. on Thursday. The index dropped to 55.9 in November from 59.1 in October, missing expectations for a decrease to 58.0.
A reading above 50 indicates a growth in the service sector.
The decrease was mainly driven by declines in the business activity, new orders, and employment sub-indexes.

The business activity/production index slid to 58.2 in November from 63.0 in October.
The ISM's employment index was down to 55.0 in November from 59.2 in October.
