Stocks closed higher after struggling to find direction much of the day amid light volume and ahead of a week filled with economic data.
The Dow Jones Industrial Averagerose 47.53 points, or 0.5 percent, to close at 10,462.77. The blue-chip index was up 14.84 points for the week, or 0.14 percent. With this week's action, the Dow edged into positive territory for the year, up 0.3 percent.
General Electric , Pfizer and Merck led the Dow higher for the week, while Hewlett-Packard and American Express fell.
The S&P 500 rose 5.37 points, or 0.5 percent, to 1,109.55. The broad index rose 5 points, or 0.5 percent, for the week, but is still lower for the year. The S&P was pushed higher by JDS Uniphase, which rose 11.8 percent for the week, and Oracle, which rose 9.3 percent.
The Nasdaq rose 6.28 points, or 0.3 percent, to 2,242.48. The tech-heavy index rose 8.73 points this week, or 0.4 percent, but is still slightly down for the year. Oracle also pushed the Nasdaq higher, as did Adobe , which rose 9.2 percent.
The CBOE Volatility Index, widely considered the best gauge of fear in the market, fell below 22.

All the major indexes are up more for the month: the Dow rose 4.5 percent, the S&P 500 rose 5.7 percent and the Nasdaq rose 6.1 percent. Volume has been light all week, however, with fewer than 1 billion shares changing hands daily on the New York Stock Exchange.
On Friday, only 756 million shares traded on the NYSE, with advancers outpacing decliners nearly 2 to 1.
"Volume is still very, very light in this market, and news is light as well," said Alan Gayle, senior investment strategist at RidgeWorth Investments. "The market is drifting higher in the absence of any definitive, fundamental news."

Similarly, Texas Instruments slipped after the semiconductor giant narrowed its earnings and revenue outlook but kept the mid-point of its forecast range. Stifel Nicolaus and Jefferies both cut their price targets on TI to $29 from $32 and $37, respectively.

In the day's economic news, the government reported earlier Friday that U.S. wholesale inventories soared 1.3 percent in July, much better than the forecasted 0.5 percent. While positive, Gayle at RidgeWorth Investments described the growth as "transitory."
"Our expectation is those gains won’t continue as businesses become more comfortable with what they own on hand," Gayle said.
President Obama held a press conference where he faulted Republicans for stalling progress on turning around the economy.

Next week also features several key economic releases. The two “market movers” will be Tuesday's retail sales and Wednesday's industrial production, said Peter Cardillo, chief market economist at Avalon Partners.
Cardillo said he is optimistic the numbers will reveal the worst news on the economy is past. If the data proves him right, the market will move higher, he said.
