Taiwan Semiconductor Manufacturing Co. posted its slowest monthly revenue growth in more than a year, lending credence to concerns that the artificial intelligence stock rally isn’t justified by the industry’s business prospects.

TSMC, the main chipmaker to AI leader Nvidia Corp., posted a 16.9% rise in sales for October, the slowest pace since February 2024. Still, that tracks with the average analyst estimate for a 16% sales increase in the current quarter. The company has also been grappling with a strengthening local currency that may have affected TSMC’s reported revenue. Its shares stood largely unchanged in Taipei Tuesday.
