The Globe and Mail reports in its Wednesday edition that U.S. and Canadian stocks ended higher on Tuesday, with Nvidia and other artificial-intelligence-linked technology shares recovering from sharp losses the previous day. A Reuters dispatch to The Globe says Nasdaq jumped 2 per cent and AI chip leader Nvidia rose 8.9 per cent, a day after its 17-per-cent drop Monday. The S&P 500 technology sector rallied 3.6 per cent, while an index of semiconductor shares gained 1.1 per cent. Apple shares rose 3.7 per cent. Investors were eager to hear from Apple, Microsoft and others when they report quarterly results later this week. The tech sell-off followed Chinese start-up DeepSeek's launch of AI models, which it said were on par or better than industry-leading U.S. rivals at a fraction of the cost. "We're getting the typical bounceback rally you'd expect when you have news that's not very specific and more of a potential for a future change," said Rick Meckler at Cherry Lane Investments in New Vernon, N.J. Nvidia's forward price-to-earnings ratio had hit its cheapest since December, 2023. The S&P/TSX Composite Index ended up 130.30 points at 25,419.45, after posting on Monday its first daily decline in two weeks.
