(Reuters) - U.S. stocks closed lower on Friday as data showed the economy contracted in the first quarter but indexes still posted gains for the month.
Transportation shares also weighed on the market, extending recent losses. The Dow Jones transportation average (DJT) fell 0.8 percent, putting it just shy of correction territory, almost 10 percent below its 2014 high.
Data showed the U.S. economy contracted at a 0.7 percent annual rate in the quarter, a sharp turnaround from the earlier estimate of growth of 0.2 percent.
Weak reports on factory activity in the Midwest and consumer sentiment for May suggested that the growth pace was modest early in the second quarter.
"We had some weak numbers, but it's the end of the month for the trading of May, which can sometimes cause a selloff. It's also Friday and Greece worries are still in the marketplace," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
U.S. Treasury Secretary Jack Lew repeated warnings on Friday not to minimize the global stability risk of Greece sliding out of the euro zone.
