Stocks take U-turn

What started as a good-sized rally is ending on a sour note, with the Dow down around 100 points with just a few minutes of trading to go. There are lots of explanations making the rounds, from a rising dollar to falling commodity prices to more worries about Bank of America being able to repay its bailout funds. Pick your poison. Here's a quote from a WSJ story that sums things up:

"The action today is very impulsive and that has added a little more credence to the fear there could be a larger correction in equity markets coming," said Christian Bendixen, director of technical research for Bay Crest Partners.
