The Globe and Mail reports in its Wednesday edition that North American stock markets closed mixed on Tuesday, as U.S. Treasury yields surged and shares of chipmakers fell after the Biden administration said it planned to halt shipments of advanced AI chips to China. A Reuters dispatch to The Globe says that Nvidia fell 4.7 per cent, even though the world's most valuable chipmaker said it does not expect a near-term meaningful effect on financial results from the curbs. U.S. Treasury yields rose on robust economic data. The 10-year U.S. Treasury note jumped almost 15 basis points, while the two-year surged almost as much in its biggest daily advance since early July, reaching 17-year highs. Retail sales in the U.S. in September increased 0.7 per cent, the Commerce Department said, while data for August were revised higher. Economists had forecast retail sales rising 0.3 per cent in September. "Good news could be bad news for the stock market because it implies that the [Federal Reserve] is going to leave interest rates higher for longer," said Anthony Saglimbene, chief strategist at Ameriprise Financial in Troy, Mich. The S&P/TSX composite ended up 72 points at 19,692.80, its highest closing level since Sept. 25.
