Wednesday begins with the release of November's ADP Employment report at 8:15 AM ET that tracks changes in private-sector jobs, using the company's payroll processing clients as a base. While it does draw attention, it is my opinion that it is overrated and is not a true reflection of the broader employment picture. It also is not very accurate in predicting results of the monthly government report that follows a couple days later. Still, because we sometimes see a noticeable reaction to the report, it is on this week's calendar. The markets are expecting to see 127,000 new private-sector payrolls last month. A much smaller number would be considered good news for mortgage rates.
