Sounds like today is going to be another fun day at the markets:

Japanese share prices plunged 9.38 percent Wednesday, the biggest loss in more than two decades as panic-selling erupted over the global financial crisis.

UPDATE, 10:50 AM: The Dow fell more than 200 points at the opening bell, then rallied more than 350 points within the next 35 minutes, and is now plummeting again. I think they call this "volatility." The S&P 500 is behaving similarly. So far, not as bad as Europe or Asia, though.
