Today's late rally tied to breaking news of President-elect Obama's naming Timothy Geithner as Treasury Secretary for the next administration, but there was also an end of week bargain-buying hunt. Today was also options expiration. Whatever the real determination was, at least it was not yet another miserable day of relentless selling.

Here were today's unofficial closing bell levels:

DJIA: 8,046 (+6.5%)
Nasdaq: 1,384 (+5.2%)
S&P 500: 800 (+6.3%)
