br The three main U.S. stock indexes rose on Thursday, as bank and energy stocks climbed. The gains come after a continuing boost from the U.S. tax overhaul, which was passed by Congress earlier this week. Energy and financial stocks led gains among the 11 major S&P sectors. Before Thursday, energy underperformed this year, with a 4.1 percent loss year-to-date. Some analysts suggested Thursday’s gains reflected an end-of-year rotation to value stocks.
