TORONTO, March 17 (Reuters) - Toronto’s main stock index closed higher for a sixth straight session on Tuesday with the latest charge by the resource-heavy index driven by energy issues as the price of oil rose.
It was the second straight session where the index ended at its highest closing level in over a month. Improved sentiment has helped the market rally sharply from the five-year low it hit earlier in March.
The lion’s share of the latest gain was powered by the 4 percent rally in the influential energy group as the price of oil rose over $2 a barrel.
Shares of Canadian Natural Resources (CNQ.TO), one of the key driver’s behind the index’s gain, rallied 4.89 percent to close at C$50.02, while EnCana Corp (ECA.TO) shares rose 2.9 percent to C$51.50.
“In terms of the market downturn we had the week before last, I really believe a number of stocks were in an oversold position and obviously the market has tended to agree with us,” said Gareth Watson, Canadian equity advisor at ScotiaMcLeod.
“But I wouldn’t be surprised at the least if over the next coming days we see some of those names pull back because of the short term momentum that they had to the upside.”
