HERE COMES ISM NON-MANUFACTURING DATA...

The Institute for Supply Management will release its survey of non-manufacturing data for May at 10 a.m.

Consensus is for a slight increase to 55.5, from 55.2.

We doubt there'll be a repeat from Monday's debacle involving ISM'S release of manufacturing data, which it had to revise twice.

But we'll be on the look out for any irregularities.
