TORONTO, April 21 (Reuters) - Canada’s main stock exchange turned negative shortly after the open, as weaker natural resource stocks and bank issues, the index’s most influential groups, dragged the market lower.
The Toronto Stock Exchange’s S&P/TSX composite index fell 42.98 points, or 0.28 percent, to 15,369.62. Four of the index’s 10 main sectors declined. (Reporting by Solarina Ho)
