Stocks erased their gains Friday and logged their worst month in nearly a year as investors shrugged off some encouraging economic data and techs took another hit.
The Dow Jones Industrial Average shed 53.13, or 0.5 percent, to close at 10,067.33. The S&P 500 dropped 1 percent and the tech-heavy Nasdaq lost 1.5 percent.

But traders were slightly worried about a couple of points in the GDP report: The sharp revision to the prior quarter's growth and consumer spending.
"[T]raders are viewing this [GDP] number with tepid enthusiasm," said Todd M. Schoenberger, managing director of LandColt Trading in San Antonio, Texas. "The biggest disappointment was the print on consumer spending, which only contributed 1.44% to GDP," he said. "Considering 70% of GDP comes from the American consumer, the outlook for future quarters still looks bleak considering the labor situation in the country."
Also weighing on the market were worries about fiscal stability in some European countries, including Greece, Portugal and Spain.
