TORONTO, Dec 14 (Reuters) - Canada's main stock index fell on Tuesday to its lowest level in nearly two weeks as stronger-than-expected U.S. inflation data and worries about the economic impact of the coronavirus weighed on investor sentiment.

The Toronto Stock Exchange's S&P/TSX composite index ended down 99.88 points, or 0.5%, at 20,648.57, its lowest closing level since Dec. 3.

The index has fallen for five straight days, its longest losing run since August.

"People should be prepared for a bumpy sleigh ride into the end of the year," said Barry Schwartz, chief investment officer at Baskin Wealth Management. "Inflation numbers in the U.S. are hotter than expected and worries about COVID seem to be never ending."

Market sentiment globally was downbeat as data showing U.S. producer prices jumped 9.6% in the 12 months through November supported bets of a faster withdrawal of stimulus by the Federal Reserve. The U.S. central bank will release its policy decision on Wednesday.

The energy group fell 1.6%, pressured by lower oil prices. U.S. crude futures settled 0.8% lower at $70.73 a barrel.

Technology was down 1.5%, while the materials group, which includes precious and base metals miners and fertilizer companies, lost 0.8%.

Canadian miner Noront Resources Ltd said it plans to negotiate directly with Australian billionaire Andrew Forrest's Wyloo Metals on the company's raised buyout offer.

Its shares ended 0.9% higher. (Reporting by Fergal Smith; Additional reporting by Sruthi Shankar and Anisha Sircar in Bengaluru; Editing by Peter Cooney)
