The Globe and Mail reports in its Tuesday edition that Canada's resource-heavy main stock index ended Monday's trading session at a two-week high, led by gains in materials and energy in quiet end-of-summer trading. A Reuters dispatch to The Globe says that Wall Street's major indexes also closed higher as traders awaited economic data from Canada and the United States this week. "Today TSX is outperforming a little bit on the back of financials and commodities and gold," said Diana Avigdor at Barometer Capital Management. "It's also the dog days of summer. Markets are going to lurch up and down for the rest of the week ahead of a long weekend." Investors were still digesting Friday's comments from U.S. Federal Reserve chairman Jerome Powell that the central bank may need to raise interest rates further to ensure inflation is contained. There is some relief that Mr. Powell was not particularly hawkish in his comments. The S&P/TSX Composite Index rose by 189.39 points to 20,025.14. Energy was up 1.5 per cent, as oil prices held steady on Monday, pressed by worries that further U.S. interest rate increases could dent demand but supported by a potential supply disruption from a tropical storm off the U.S. Gulf Coast.
