The Globe and Mail reports in its Wednesday edition that Canada's main stock index rose on Tuesday, led by energy and technology shares, as investors took advantage of U.S. President Donald Trump's backdown on his tariff threat. A Reuters dispatch to The Globe says that U.S. stocks also saw gains amid hopes for a trade breakthrough between the U.S. and China. Strong U.S. corporate earnings also buoyed investor optimism. The S&P/TSX Composite Index ended at 25,279.35, up 37.59 points, ending two straight days of heavy losses. "The President was so quick to offer a 30-day stay of execution to Mexico and Canada, so you get the idea that maybe what he's really trying to do is embrace a quick declaration of victory which doesn't change much from a trade perspective," said Sam Stovall, chief investment strategist at CFRA Research. Toronto's energy group was up 1.1 per cent, helped by a gain of 4.4 per cent for the shares of Cenovus. TMX Group was among the biggest advancers. Its shares rose 8.3 per cent as the stock exchange operator reported fourth-quarter profit and revenue above estimates. Financials, however, fell 0.9 per cent. Investors worry that lingering trade uncertainty could weigh on the domestic economy.
