Details of the September 2016 US Markit services flash report 27 September 2016
Prior 51.0
Employment 51.1 vs 51.9 prior
New orders 52.0 vs 52.8 prior
Composite 52.0 vs 51.5 prior
New orders 51.8 vs 52.8 prior
Employment 51.4 vs 51.6 prior (Lowest since June 2012)
That's employment to the lowest since March 2013. Last month it was at the lowest since 2014. That's not a good component to show it's starting to wilt when the Fed are still messing around over a rate hike.
Remember though, although some components are lower, they are still in expansion. The trouble starts if elements start falling into contraction.
