A selloff in energy shares led U.S. stocks lower, after the biggest rally in two months left the Standard & Poor’s 500 Index near its all-time high.

Noble Energy Inc. fell 5.9 percent after agreeing to buy Rosetta Resources Inc. for $2.1 billion. Rosetta jumped 27 percent, boosting the Russell 2000 Index. Exxon Mobil Corp. lost 1.4 percent as oil prices slipped. Actavis Plc advanced 3.4 percent after posting better-than-estimated first-quarter earnings. Dean Foods Co. added 6.9 percent as earnings topped analysts’ estimates and the company boosted its outlook.

The Standard & Poor’s 500 Index declined 0.3 percent to 2,110.44 at 12:28 p.m. in New York. The Dow Jones Industrial Average slipped 56.68 points, or 0.3 percent, to 18,134.43. The Russell 2000 rose 0.5 percent, while the Nasdaq Composite Index was little changed.

Stocks jumped the most since March on Friday after a report showed hiring bounced back in April, signaling companies are confident the economy will recover from a winter slowdown. The gain helped push the S&P 500 up 0.4 percent for the week.
