TORONTO, Feb 24 (Reuters) - Toronto's main stock index slipped into negative territory early on Thursday afternoon as investors took profits in energy and gold-mining stocks after healthy recent gains in those groups.
The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE was down 0.82 of a point at 13,955.37.
The index's materials group, home to miners, was down 1.41 percent, while the energy group was down 0.9 percent. Oil and gas stocks had advanced in eight of the previous nine sessions due to the upheaval in North Africa. (Reporting by Solarina Ho; editing by Peter Galloway)
