U.S. stocks opened higher Wednesday, as investors resumed buying under-loved energy and financial stocks, following a late-session downturn the day before. Tuesday’s moves had been initially propelled by a continued slowdown in the number of new COVID-19 cases and optimism over treatment options. The Dow Jones Industrial Average added 266 points, 0.1%, opening near 27,953, while the S&P 500 index rose 29 points, 0.9%, opening near 3,362. The tech-heavy Nasdaq Composite index opened near 10,882, up 99 points or 0.9%. Investor enthusiasm comes despite a lack of progress toward additional stimulus aid to offset the impact of closing the economy to contain the virus.
