Here comes Markit services PMI ...

Markit Economics will release its preliminary report on the US services sector during September at 9:45 a.m. ET.

According to Bloomberg, economists estimate that the flash purchasing manager's index was 51.2. When the index is above 50, it indicates that the sector is in expansion.

The previous flash report showed that the sector, which creates most of America's jobs, struggled to grow employment.

The report based on Markit's survey of service providers also showed that they hoped client spending picks up after the November elections.
