The Globe and Mail reports in its Thursday edition that U.S. and Canadian stocks closed higher on Wednesday, with the S&P 500 and Nasdaq each rallying more than 1 per cent as earnings from neocloud player CoreWeave cooled investor concerns about the durability of the AI trade, while Nvidia stabilized after two straight sessions of sharp declines. A Reuters dispatch to The Globe says CoreWeave shares surged 24.7 per cent. The company said it would become profitable in the first half of 2028 on an adjusted basis, seeking to reassure investors that strong demand and customer commitments could support its debt-fuelled expansion. Sentiment improved across artiticial-intelligence infrastructure stocks, including Nebius and Applied Digital. Nvidia advanced 2.9 per cent amid worries over chief executive officer Jensen Huang's relationship with an alleged Chinese spy. The enthusiasm for tech Wednesday travelled north of the border. The S&P/TSX Composite Index added 241.27 points to close at 36,411.72. The S&P 500 technology index was up 2.7 per cent. The Canadian energy sector added 2.33 per cent as Brent crude traded up 1.13 per cent at $92.5 (U.S.) per barrel. The financial sector index was up 0.74 per cent.
