Wall Street edges up as oil rebounds

U.S. stock indexes were slightly higher on Wednesday as a recovery in oil added to the boost from earnings reports that beat tempered expectations. A three-day strike by Kuwaiti oil workers had driven prices higher and helped the S&P 500 breach 2,100 on Tuesday, about 30 points shy of its record high. A recent rebound in oil and the U.S. Federal Reserve's accommodative monetary policy helped the index recover from a steep selloff earlier this year.
