NEW YORK, March 11 (Reuters) - U.S. stocks fell in afternoon trading on Tuesday after swinging between gains and losses for most of the session as the lack of major corporate earnings or market-affecting data kept trading directionless.
U.S. wholesale inventories rose more than expected in January, as companies built up stocks of autos and machinery, but sales posted their largest decline in nearly five years.
Retailers in the news included American Eagle and Urban Outfitters, their shares down sharply after disappointing outlooks.
"When you get a slow data week, markets tend to get a little jittery and slow," said Quincy Krosby, market strategist at Prudential Financial in Newark, New Jersey. "The market has been up very quickly and is sort of waiting for a next catalyst."
The Dow Jones industrial average fell 46.93 points or 0.29 percent, to 16,371.75, the S&P 500 lost 6.04 points or 0.32 percent, to 1,871.13 and the Nasdaq Composite dropped 11.349 points or 0.26 percent, to 4,323.099. Continuación...
