The Globe and Mail reports in its Wednesday edition that Canada's main stock index rallied by the most in nearly six weeks on Tuesday, with resource stocks leading the gains as commodity prices rose and the United States left out energy and critical minerals from a list of proposed new tariffs on Canadian goods. A Reuters dispatch to The Globe says Wall Street's main indexes also rose, with a recovery in semiconductor shares helping to shift the focus away from the latest developments in the Middle East, while investors awaited major tech earnings for clues on the future of the artificial-intelligence trade. The S&P/TSX Composite Index ended up 408.76 points, or 1.2 per cent, at 35,369.08, after three straight days of declines. "It does help the Canadian investment landscape the fact that, one, there is still only a narrow set of exports that are targeted and, two, that there are carve-outs for the energy and other commodities that we ship to the United States on a usual basis," said Bipan Rai at BMO Global Asset Management. The materials group jumped 5 per cent as gold and copper prices climbed. Hudbay Minerals Inc was among the biggest advancers, with its shares gaining 10.5 per cent. Energy added 2.2 per cent.
