TORONTO, March 9 (Reuters) - Canada's main stock index edged higher on Thursday as energy shares rebounded after sharp losses the day before even as U.S. oil prices fell below $50 a barrel, while the materials group also gained ground.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was up 9.42 points, or 0.06 percent, at 15,506.40, shortly after the open. Just three of the index's 10 main groups were higher.
