Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of E*TRADE Financial (Nasdaq: ETFC) fell 14% today after the company reported a loss during the fourth quarter.

So what: The company's loss in the fourth quarter improved to $6.3 million in the fourth quarter, or $0.02 per share, from a $24 million loss last year, but analysts expected more. Experts were expecting $0.20 in earnings per share, and shares have taken a dive as a result.
