TSMC Stock: Major AI Player
The incident underscored the heightened competition in the semiconductor market, especially with the rapid advance of artificial intelligence.
TSMC is a major player in AI as the world's biggest semiconductor contract manufacturer. The company's customers include the world's biggest tech companies, including Nvidia and Apple.
The company last month posted second-quarter results that easily beat Wall Street estimates. TSMC Chief Financial Officer Wendel Huang said the company got a lift from "robust" demand in AI and high-performance computing.
"Moving into third quarter 2025, we expect our business to be supported by strong demand for our leading-edge process technologies," Huang said in a statement.

TSM stock has a Relative Strength rating of 90, down from 91 a week ago, according IBD MarketSurge.
