Stocks unsteady after GDP data NEW YORK Stock indexes were mixed in early trading on Wall Street after the government reported U.S. economic growth that wasn't as strong as economists had forecast. The Dow Jones industrial average hung on to modest gains, rising 13 points to 14,713 an hour after the opening bell Friday. The Standard & Poor's 500 index was down more than four points at 1,580, while the Nasdaq Composite was off 13 at 3,281. The government reported that the U.S. economy expanded at an annual rate of 2.5 percent in the first three months of the year. That's better than the 0.4 percent growth rate in the final three months of last year, but not as strong as the market had been expecting. Homebuilder D.R. Horton jumped 6 percent after reporting a surge in revenue. Amazon plunged, falling $17.25 to $257, a loss of more than 6 percent. The online retailer surpassed analysts' earnings expectations, but issued gloomy guidance for coming quarters.
