TORONTO, Sept 17 (Reuters) - Toronto's main stock index finished lower on Thursday as investors decided to take profits after five straight sessions of gains.
The pullback was broad, with eight of the index's 10 main groups pacing lower. The two advancing groups, financials and health care, rose 0.45 percent and 0.18 percent, respectively.
"It feels like a pause more than anything else," said Elvis Picardo, vice-president of research at Global Securities in Vancouver. "The point to note also is the market continues to display pretty impressive resilience."
Notable decliners included First Quantum Minerals (FM.TO), which fell 8.7 percent to close at C$64.25 after analysts downgraded the stock. First Quantum said on Wednesday it had suspended its copper project in the Democratic Republic of the Congo.
Gold miner Royal Gold RGL.TO gave up 4.6 percent to end at C$47.79. BlackBerry maker Research In Motion RIM.TO fell 1.2 percent to C$88.25.
Amid the winners, fertilizer producer Potash Corp (POT.TO) rose 2.85 percent to C$103.25. Private-equity firm Onex Corp OCX.TO rose 2.1 percent to C$24.65.
The S&P/TSX composite index .GSPTSE dropped 27.37 points, or 0.24 percent, to end at 11,528.23. Among its falling components, the energy group edged down 0.4 percent, while the resource-heavy materials group gave up 1.37 percent.
