The Globe and Mail reports in its Thursday edition that Canada's main stock index rose to a record high on Wednesday as higher commodity prices boosted energy and metal-mining shares. A Reuters dispatch to The Globe says Wall Street edged lower, with investors awaiting key earnings reports to gauge the health of a market rally fed by enthusiasm for artificial intelligence. After months of gains that lifted the major U.S. indexes from their March lows, momentum has been wobbling with uneven trading in heavyweight semiconductor stocks and weakness in software companies. The Philadelphia SE Semiconductor Index ended up 0.4 per cent after three days of losses that confirmed it was in a bear market late last week. The crowded earnings calendar leaves markets vulnerable to sharper swings this week, while geopolitical tensions added another layer of caution. Crude oil futures recorded their highest settlement since June 11, up around 3 per cent on the day as Yemen's Iran-backed Houthi militia threatened shipping in the Red Sea. The S&P/TSX Composite Index ended up 116.03 points at 35,485.11, a record closing high. The materials group advanced 2.4 per cent. Gold rose 1.3 per cent. Energy stocks added 1.3 per cent.
