The Dow Jones industrial average tumbled to its lowest close in more than six years today, dropping 89.68 points, or 1.2%, to close at 7,465. Financial stocks were the hardest hit: Citigroup closed at $2.51, the lowest it's been in the bank's history. American Express dropped 8.7% to end the day at $12.87, a level it hasn't seen since 1972. In more positive news, this NYSE floor trader is totally getting lucky tonight, so at least he's got that going for him. [NYP, MW]
