I disagree. The stockholders have lost almost all of their investment. To say they haven't taken the brunt of this is ridiculous.
As for the mark to market... this is the exact environment to demonstrate the flaws in mark to market.
If Bank A and Bank B both own asset C, Bank B comes under financial stress and firesales its assets to raise capital... what is the real value of the asset they sold? The firesale price? Should Bank A suffer just because Bank B ran into problems?
Firesales create a downward spiral. Especially in Banks that rely on their assets to maintain capitalization.
I believe a temporary suspension should have been done 6 months ago. But doing it today is better than nothing. That said, IF they suspend mark to market, the Banks MUST show complete transparency in regards to their assets. Otherwise you end up with the same downward spiral in that investors would not know the true holdings risk.
As for the fed taking over distressed assets... to act like they have no value is simply ridiculous. All of those distressed loans will not default. So long as the government doesn't overpay for the assets, they will have the ability to get a return. But again, IF the banks participate in such a plan then future gains in the valuations of the banks need to be shared with the tax payers to help offset the portion of the loans that do go bad.
