Shares of Exxon Mobil XOM.N surged 4.6 percent, also the biggest percentage gain since late August, to $79.12, while Chevron CVX.N jumped 5.1 percent to $85.47, among the biggest boosts to the Dow and the S&P 500. U.S. CLc1 and Brent LCOc1 oil prices ended more than 2 percent higher. The SPDR Energy Select Sector exchange-traded fund XLE.P rose 4.3 percent.
