TORONTO, July 22 (Reuters) - Toronto's main stock index turned higher on Wednesday, helped by a reversal in financials, though gains were tenuous as the hefty energy and materials groups dragged on the resource-heavy index.
The S&P/TSX composite index .GSPTSE edged up 2.72 points to 10,518.04. The TSX had fallen more than 1 percent shortly after the open.
Eight of the index's 10 main groups were lower. Financials were up 0.6 percent, but energy and materials were both down around 0.4 percent. (Reporting by Ka Yan Ng; editing by Rob Wilson)
