The Dow Jones Industrial Average on Wednesday afternoon was trading near session highs as crude-oil futures powered shares of some of the largest energy-related companies. The Dow most recently, gained 315 points, or 1.3%, at 24,677, with shares of components Exxon Mobil Corp. and Chevron Corp. contributing about 50 point to the blue-chip gauge's late-session advance, as crude-oil futures extended their intraday climb on the back of reports that major oil producers at the Organization of the Petroleum Exporting Countries and Russia would hold current output levels steady, rather than increasing production--bullish for oil prices and stocks. At session's peak, the Dow rose about 340 points, eating into a 390-plus-point decline on Tuesday. The S&P 500 index meanwhile, jumped 1.4% at 2,726, while the Nasdaq Composite Index rallied by 0.9% at 7,465. The three main benchmarks are attempting to rebound from a rout on Tuesday, sparked by concerns that political turmoil in Italy would spill over into the broader markets.
