TSX dives to one-month low after NDP Alberta win

TORONTO (Reuters) - Canada's main stock index dropped about 1 percent on Wednesday, hitting a one-month low, as the victory of the left-wing New Democratic Party in oil-rich Alberta's provincial election hit energy shares. The Toronto Stock Exchange's S&P/TSX composite index <.GSPTSE> closed down 150.05 points, or 0.99 percent, at 15,023.89. Seven of the 10 main sectors on the index were in the red.
