The Globe and Mail reports in its Saturday, Oct. 17, edition that Wall Street ended sharply lower on Friday, with CoreWeave, Broadcom and other AI-related technology stocks under renewed pressure, while a jump in oil prices spooked traders heading into the weekend. A Reuters dispatch to The Globe reports that The TSX gained modestly, with strength in the energy sector offsetting losses in less influential tech stocks. The Nasdaq extended losses from earlier in the week, hammered by concerns that debt-laden artificial intelligence infrastructure companies may not turn profits in time to repay debts, particularly with borrowing costs expected to rise. Nvidia-backed CoreWeave slumped 12 per cent, bringing its loss over the past five sessions to about 25 per cent. CoreWeave's bonds also sold off sharply last week, pushing yields above 15 per cent. Broadcom fell 4.5 per cent, and the PHLX chip index sank 3.8 per cent in its eighth straight day of declines, its longest losing streak since 2008. Investors on Friday were also watching oil prices jump around 3 per cent. Brent touched $110 (U.S.) a barrel for the first time since May on worries that escalating tensions in the Middle East could further tighten supplies.
