* TSX rises 57.47 points, or 0.43 percent, to 13,392.20 * Six of 10 main index sectors advance * Weekly gain strongest in five months * Enbridge in focus ahead of decision on pipeline By John Tilak TORONTO, Dec 19 (Reuters) - Canada's main stock index reached its highest level in two weeks on Thursday after a decision by the U.S. Federal Reserve to trim its monetary stimulus program helped drive gains in the financial and energy sectors. The Toronto market basked in the afterglow of the Fed announcement, which came in on Wednesday, recording a weekly gain of 2 percent, it strongest performance in more than five months. However, a sharp drop in bullion dragged the commodity price to a six-month low and triggered a decline in gold-mining shares. Investors bracing for a selloff after the Fed statement on Wednesday were pleasantly surprised by the market reaction. Global equity markets rallied after the news, and Toronto stocks recorded a 1.2 percent jump in Wednesday's session. "The uncertainty that was hounding the market for the last several months was removed," said Shailesh Kshatriya, associate director for client investment strategies at Russell Investments Canada. "The Fed was very careful in the way it massaged the language, that tapering will be gradual and tightening is still a long time away," he added. Investors were encouraged by the fact that increasing strength in the world's biggest economy and greater confidence in the recovery led to the Fed decision. The U.S. central bank cut the pace of its monthly asset purchases and suggested its key interest rate would stay low longer than previously promised. "The black clouds on the horizon, which were the political debt ceiling and when tapering arrives, have all gone by," said David Cockfield, managing director and portfolio manager at Northland Wealth Management. "It's hard to find some reason to be overly pessimistic here." "The risk element has gone out of the market," he added. "It's a more settled and benign environment for equities." The Toronto Stock Exchange's S&P/TSX composite index closed up 57.47 points, or 0.43 percent, at 13,392.20, after reaching 13,396.62, its highest level since Dec. 3. Six of the 10 main sectors on the index were higher. Financials, the index's most heavily weighted sector, climbed 0.8 percent. Royal Bank of Canada, the country's biggest lender, rose 1.1 percent to C$70.58, having the biggest positive influence on the market. Manulife Financial Corp gained 2.6 percent to C$20.75. Higher oil prices helped support shares of energy producers. Canadian Natural Resources Ltd advanced 1.7 percent to C$35.02. Gold-mining shares dropped nearly 2 percent, reflecting a 3.8 percent decline in bullion prices. Goldcorp Inc shed 1.6 percent to C$22.24, and Barrick Gold Corp gave back 2.2 percent to C$17.68. Investors also focused on Enbridge Inc, as Canada's largest pipeline company is expected to find out on Thursday whether regulators will recommend approval of its proposed C$6 billion ($5.7 billion) Northern Gateway oil pipeline. The stock was up 1.1 percent C$45.33.
