No more WMT monthly "earnings"

A big thanks to Ernst from http://www.thetapositive.com for pointing out that WMT is no longer going to release monthly same-store-sales reports, and move to just a quarterly earnings announcement. Therefore, I no longer need to fear the first week of every month when I have a WMT trade on.

From WMT's previous monthly report on May 7, 2009:

Policy Change for Reporting Comparable Store Sales
“At the start of this fiscal year, Wal-Mart revised its approach to providing guidance for sales. We went from providing guidance for monthly sales to forecasting a guidance range for our U.S. businesses for the full 13-week period,” said Tom Schoewe, executive vice president and chief financial officer for Wal-Mart Stores, Inc. “Moving forward, we will no longer report monthly sales. We will provide comparable store sales results on a 13-week basis, along with guidance for the upcoming 13-week period. And, we will release this information during our scheduled quarterly earnings calls.
