The S&P/TSX Composite Index edged 0.1% lower to close at 31,483 on Monday, as losses in technology and energy outweighed gains in financials while investors digested fresh Canadian inflation data. E-commerce heavyweight Shopify led the decline, falling 2.6% in step with US peers amid renewed concerns over the profitability and financing of large-scale AI investments. Energy majors Canadian Natural Resources, Suncor, Imperial Oil, and Cenovus also underperformed, each sliding between 1.1% and 2.3% as crude oil sank to its lowest levels since early 2021. Offsetting some of the pressure, financial heavyweights RBC, TD Bank, and Manulife each rose around 0.8%, limiting the index’s decline. On the macro front, headline inflation held steady at 2.2% in November, unchanged from October and below expectations of 2.3%, while the Bank of Canada’s preferred trim mean eased to a ten-month low of 2.8%, reinforcing the view that inflation is gradually converging toward the 2% target.
