Either there is a huge cash infusion to the people who need it least or the dollar will take a dive on world currency markets, making US stocks look cheap to overseas institutional investors.

I don't see either happening any time soon. I don't know if the market has bottomed out for now, but I do expect to see the Dow above 30K sooner rather than later, but that's just me. There are only so many places for the guys who pocketed $$ at the relative top of the market to put the cash now that it's lower.
