Here comes Chicago PMI ...

The Institute of Supply Managers and MNI Indicators will release their monthly report on business activity in Chicago at 9:45 a.m. ET.

Economists forecast that the purchasing manager's index rose to 52 in September from 51.5, according to Bloomberg.

A reading above 50 indicates that business activity is still in expansionary territory.

Four of the five readings of the business barometer fell from July to August; only the employment component increased.

"On a trend basis, though, the July-August growth rates paint a slightly better picture - albeit still weak - than that seen earlier in the year," said Lorena Castellanos, senior economist at MNI Indicators, in the previous report.
