A surge in energy stocks is challenging climate-conscious money managers who beat the market for years when the sector struggled but are now missing out on Wall Street's hottest trade. The S&P 500 energy sector has rebounded 54% this year, outpacing the broad index's 21% climb and leading the second-best-performing group by about 16 percentage points. That would mark the third-largest such gap between the top two sectors since 2000, according to Dow Jones Market Data. Devon Energy has a stellar performance this year with total gains at 163%.
