Financial shares , which rose 2 percent early in the session on news that Bank of America BAC.N will get aid from the U.S. government, were down 2 percent late in the morning as the market judged the bailout was not enough to overshadow signs of more fallout from the credit crisis for the financial sector.
Higher prices for gold and oil helped to power gains in the energy and materials sectors, which together account for about 40 percent of the overall index and managed to cushion the TSX's slide. The materials group was up 1.9 percent and the energy was up 0.67 percent.
Among the key stocks behind the market's fall were Bank of Nova Scotia BNS.TO, down 4.5 percent at C$29.94, and Toronto-Dominion Bank TD.TO, down 3.5 percent at C$42.53.
