Wall Street's wild Christmas week rolls on. The Dow Jones Industrial Average fell more than 430 points in the first hour of trading Thursday, a day after notching its biggest-ever one-day point gain.

At 10:30am, the S&P 500 index had fallen 41 points, or 1.7%, to 2,426; the Dow was down 387 points, or 1.7%, to 22,492; and the tech-heavy Nasdaq was down 135 points, or 2%, to 6,419.
