Housing Sales Have Been Overcounted, Meaning the Housing Market is in Worse Shape Than We Thought

The economic bad news just keeps on coming:

Data on sales of previously owned U.S. homes from 2007 through October this year will be revised down next week because of double counting, indicating a much weaker housing market than previously thought.

The National Association of Realtors said a benchmarking exercise had revealed that some properties were listed more than once, and in some instances, new home sales were also captured.

"All the sales and inventory data that have been reported since January 2007 are being downwardly revised. Sales were weaker than people thought," NAR spokesman Walter Malony told Reuters.

"We're capturing some new home data that should have been filtered out and we also discovered that some properties were being listed in more than one list."

I wonder how the stock market will react to this?
