* TSX up 63.83 points, or 0.42 percent, at 15,139.01 * Eight of 10 main index sectors advance * First Quantum jumps 8.4 percent, Teck rises 7.8 percent By John Tilak TORONTO, Nov 21 (Reuters) - Canada's main stock index rose to its highest in nearly two months on Friday, driven by gains in most major sectors, as investors cheered a move by China to cut interest rates. The surprise announcement was the first time in two years that China had cut rates, following signals that the pace of growth in the world's second-biggest economy was slowing. The move helped drive gains in the prices of commodities such as gold, copper and oil; and that pushed up shares in the mining and energy sectors. The Canadian equity market is heavily weighted in natural resource stocks, and the country is a major exporter of commodities. The benchmark TSX was up for the sixth day and was on track to record its sixth consecutive weekly gain, recovering from a sharp market correction in October. "It's remarkable how rapidly investors' opinion has changed from the beginning of October, when it was gloom and despondency," said Gavin Graham, chief strategy officer at Integris Pension Management Corp. "If you accept that the Chinese are cutting rates because they want to actually get the economy moving forward again, presumably that's going to lead to some rebound in commodity prices," he added. The Toronto Stock Exchange's S&P/TSX composite index was up 63.83 points, or 0.42 percent, at 15,139.01. Eight of the 10 main sectors on the index were higher. Shares of energy producers rose 2.2 percent, with Suncor Energy Inc gaining 2.3 percent to C$40.62 and Canadian Natural Resources Ltd advancing 2.1 percent to C$43.04. The materials sector, which includes mining stocks, climbed 1.6 percent. First Quantum Minerals Ltd shot up 8.4 percent to C$19.34, and Teck Resources Ltd jumped 7.8 percent to C$19.63.
