Toronto stocks ended a two-day rally and finished lower on Thursday on profit taking in energy and materials shres.

The S&P/TSX composite index closed down 83.45 points, or 0.64%, at 12,927.28.

Overall, eight of the 10 TSX index main groups fell. The energy sector led the decline, dropping 1.8% along with U.S. crude, which ended below US$55 on profit-taking and as increased stockpiles countered the impact of cold weather on prices.

Disappointing earnings from Petro-Canada and Suncor Energy Inc. also weighed on the energy group. Petro-Canada lost 63¢, or 1.4%, to $44.37, while Suncor sagged $2.65, or 3%, to $86.81.

The materials group, which includes gold mining shares, also dragged the broader index lower despite firmness in underlying commodities.

Barrick Gold shed 24¢, or 0.69%, to $34.65, while Kinross Gold Corp. lost 6¢, or 0.39%, to $15.20.

Potash Corp. of Saskatchewan Inc. fell $4.03, or 2.3%, to $169.71, and Methanex Corp. dropped $3.94, or 11.3%, to $30.93. Both companies reported higher profits before the market opened.

The telecoms and industrials sectors gained 0.7% and 0.4%, respectively.

The junior S&P/TSX Venture composite index fell 14.40 points, or 0.50%, to finish at 2,869.85.

U.S. stocks ended sharply lower, as falling oil prices prompted selling in the energy sector and a rise in bond yields revived worries about rising interest rates.

The Dow Jones industrial average was down 119.21 points, or 0.94%, to at 12,502.56. The S&P 500 was down 16.23 points, or 1.13%, to finish at 1,423.90. The Nasdaq composite index was down 32.04 points, or 1.30%, to close at 2,434.24.
