(Reuters) - U.S. stocks extended their losses in late morning trading on Friday after weak GDP and consumer sentiment data added to investor concerns about the strength of the economy.
The latest data showed the economy contracted at a 0.7 percent annual rate in the first quarter, a sharp turnaround from an earlier estimate of a 0.2 percent growth pace issued last month.
Economists had expected GDP would be revised to show a contraction of 0.8 percent.
Consumer sentiment fell in May, a survey by the University of Michigan showed, while the Institute for Supply Management-Chicago Business Barometer unexpectedly fell in May.
"The data is telling us that the economy is improving but it is not super strong," said Kim Forrest, a senior equity research analyst at Fort Pitt Capital Group in Pittsburgh.
"We are looking at the first half of 2015, which is probably not as strong as investors would have liked. So that adds to today's lackluster market action."
Investors keep a keen eye on economic data for cues to help narrow down the timing of an increase in interest rates by the Federal Reserve.
"Today's market action says the rate increase is going to happen in September," Forrest added.
The GDP report also showed that corporate profits declined 8.7 percent, the largest drop in a year and the second straight quarterly fall.
Greece's ability to strike a deal with its euro zone partners by Sunday also weighed on global markets.
A euro zone official said Greece will not be able to get the money still available under its current bailout plan if it does not agree to the outline of a reforms-for-cash deal with creditors by the end of next week.
