The Globe and Mail reports in its Tuesday edition that the Nasdaq Composite fell more than 1 per cent Monday, as investors worried about demand for technology supporting artificial intelligence while they waited for results from Nvidia. A Reuters dispatch to The Globe says it was Nasdaq's third consecutive loss and its fourth daily drop of more than 1 per cent in February. The S&P 500 closed slightly lower, marking its third straight day of declines, while the Dow and Toronto Stock Exchange managed to eke out tiny gains. Investors were concerned about future demand for Nvidia's pricey AI chips as they awaited its quarterly results on Wednesday. Worries about hefty spending on the technology have mounted since low-cost AI models from China's DeepSeek rattled the industry in January. Adding to uncertainty, a TD Cowen analyst note published late on Friday reported that Microsoft has scrapped leases for sizable data centre capacity in the United States, suggesting a potential oversupply of AI infrastructure. The S&P/TSX Composite Index ended up 4.23 points. The financials sector was barely changed but the consumer staples sector climbed 2.1 per cent, with shares of food retailer Metro adding 3.1 per cent.
