You're wrong. Most all of the banks weren't even marking their toxic assets to market anyways. They are still marking Alt-A's at 95-97 cents on the dollar.
This rule change will have little effect. Wall Street just doesn't realize it yet.
We will see a Dow of 4,000 before we see a Dow of 8,800.
I suspect you are correct, this is to give the dumbo talking heads spin.
