Stocks pulled back this morning off yesterday’s heady rally. The Dow sank 77 points, after skyrocketing nearly 500 points in yesterday’s session. The S&P and Nasdaq dropped 1.3% and 1.4% respectively. AIG was the big story, with Timothy Geithner and Ben Bernanke set to testify before Congress. Geithner is expected to ask for the power to seize failing, systemically important companies, even though they're not banks.
