The Dow lost almost 3% (dropping almost 250 points) and the Nasdaq and S&P 500 both lost more than 3% today, as, CNBC reports, "volatility and uncertainty remained" with worries over "earnings, retail reports, questions surrounding the status of Treasury Secretary nominee Timothy Geithner's former housekeeper and the incoming Obama administration." So everything! Oh, and there are concerns over Citigroup, whose stock fell 23% to $4.53 and bad news from other banks, too. Retail sales fell 2.7%, double what analysts thought. Now there's news that Apple CEO Steve Jobs is taking a leave of absence due to health issues.
