Wall Street edges up as factory data shines amid oil gloom

Wall Street edged higher in choppy trading on Thursday, breaking step with sliding oil prices, as strong U.S. manufacturing data pointed to a recovery in the struggling sector. The S&P 500 has lost 5.5 percent in 2016 as oil hovers near multi-year lows. Some investors, however, said the two could soon delink as focus shifts to data and the U.S. Federal Reserve's next move on interest rates.
