U.S. stocks rose on Friday, with the Dow industrials briefly hitting 11,000 for the first time since September 2008, on an upbeat outlook from Chevron and strong inventories data that gave support to bets on an improving economy.

The Dow Jones industrial average <.DJI> added 70.28 points, or 0.64 percent, to close unofficially at 10,997.35. The Standard & Poor's 500 Index <.SPX> rose 7.93 points, or 0.67 percent, to end unofficially at 1,194.37. The Nasdaq Composite Index <.IXIC> gained 17.24 points, or 0.71 percent, to 2,454.05.

For the week, the Dow rose 0.6 percent, the S&P 500 gained 1.4 percent and the Nasdaq was up 2.1 percent. Friday's close marked the sixth straight week of gains for the three indexes, matching a streak not seen since U.S. stocks rebounded from more than 12 year lows in March 2009.
