Wall St ends up on energy shares

U.S. stocks closed higher in volatile trading on energy shares and some better-than-expected economic reports, but gains limited by rumors that Fitch ratings agency may out with a statement on U.S. downgrade.
Dow Jones Industrial Average closed slightly up after nearly 2 per cent decline since Monday.
S&P 500 and the Nasdaq also finished in positive territory.
Among the key S&P sectors, telecoms and materials dragged, while health care and energy held small gains.
