The Globe and Mail reports in its Saturday edition that U.S. stocks closed higher on Friday after a rocky start to the week, as a rebound in technology shares offset tumbling consumer stocks such as Nike. A Reuters dispatch to The Globe says megacaps extended gains from Thursday, when chipmaker Micron Technology's strong forecasts reignited optimism around AI-related shares, which had recently come under pressure over lofty valuations and debt concerns. Micron reached a record closing high on Friday, ending the day up 7 per cent. Nvidia rose 3.9 per cent as the U.S. launched a review that could allow the first shipments to China of Nvidia's second-most powerful AI chip. In Toronto, Canada's main stock index rose to a record high in heavy volume, led by gains for technology and metal mining shares, as investors bet that government stimulus and lower borrowing costs would help underpin corporate earnings. The S&P/TSX Composite Index ended up 314.92 points at 31,755.77, eclipsing the record closing high it posted on Dec. 11. For the week, the index was up 0.7 per cent, while it has added 28.4 per cent since the start of the year. Technology added 2.5 per cent even as shares of BlackBerry fell 14.1 per cent.
