All 10 major S&P sectors gained and seven of them were up over 1 percent, led by a 1.75 percent rise in the energy index . Oil rose over 4 percent as supply disruptions in Canada and elsewhere overshadowed fears of oversupply.

International stock markets were helped by solid corporate earnings in Europe, progress on Greek debt talks, and a new pledge by Japan that it was prepared to weaken the yen.

"A great triple-digit day, it's fantastic," said Jake Dollarhide, chief executive officer of Longbow Asset Management in Tulsa, Oklahoma. "People are feeling confident."
