NEW YORK, June 29 (Reuters) - U.S. stocks rose on Monday as higher oil prices boosted energy shares, and signs of life in the global economy and overseas markets renewed investor optimism on the prospects of a recovery.
Oil futures jumped almost 3 percent after Nigerian militants said they attacked a Royal Dutch Shell facility and the U.S. government said oil demand in April was revised upward from a previous estimate but was still down from a year ago.
Energy shares gained, with Chevron Corp up 1.3 percent to $66.81, and Exxon Mobil Corp adding 2 percent to $70.39.
Lifting optimism, the euro zone's economic sentiment index rose for the third month in a row, Chinese stocks reached a one-year closing high for the fourth straight session, and copper prices continued to edge higher.
"There's still buying on dips, there's still buying of this commodity trade related to China and a weaker dollar, and I think that is continuing again this morning," said Peter Boockvar, equity strategist as Miller & Tabak in New York.
The Dow Jones industrial average gained 83.66 points, or 0.99 percent, to 8,522.05. The Standard & Poor's 500 Index added 7.14 points, or 0.78 percent, to 926.04. The Nasdaq Composite Index rose 5.91 points, or 0.32 percent, to 1,844.13.
