TORONTO Jan 17 (Reuters) - The Toronto Stock Exchange's main index reversed sharply from early gains on Thursday, slipping into negative territory as materials, led by Potash Corp of Saskatchewan POT.TO, tumbled.
The S&P/TSX composite index .GSPTSE was down 3.20 points at 13,071.66, mirroring a reversal in U.S. stock markets. The TSX was up more than 100 points earlier in the session.
