The Globe and Mail reports in its Friday edition that U.S. stock markets closed mixed Thursday. A Reuters dispatch to The Globe says the S&P/TSX Composite Index closed at 34,850.21, up 114.12 thanks partly to a bounce-back in oil and gold prices. U.S. technology shares reversed early gains to move lower, weighing on the Nasdaq as investors worried about hyperscaler spending on artificial intelligence and who foots the bill. Those fears outweighed upbeat signals on AI demand from Micron and Qualcomm. Apple slid 6.1 per cent after hiking prices for iPads and MacBooks to counter surging memory and storage chip costs. Shares of Nvidia, Microsoft and Alphabet were also down between 0.5 per cent and 3.5 per cent. Micron soared 15.7 per cent after its earnings and forecasts beat Wall Street estimates. Still, concerns over debt-backed spending by hyperscalers and fears of a more hawkish Federal Reserve kept weighing on the market this week. Sandisk soared 22 per cent, while Qualcomm, Western Digital and Seagate all popped. Six of the 11 major S&P 500 sectors moved higher, led by industrial stocks which rose 2.2 per cent. Consumer discretionary and staples lost the most ground while tech stocks dropped 0.1 per cent.
