TSMC Q3 Revenue Up 51% to Record, Stock Falls
TSMC reported a 51% increase in third-quarter revenue to 1.49 trillion Taiwan dollars (EUR 41.7 billion), surpassing expectations. The semiconductor giant, a key supplier to Apple and Nvidia, continues to benefit from the AI boom and strong chip demand. However, the stock declined despite the record results. The company plans to invest EUR 52-56 billion in expanding its manufacturing facilities this year, including a joint venture with Sony for image sensors. TSMC's market capitalization is approximately USD 2.45 trillion, making it the most valuable company outside the US. The company's growth is also boosting Taiwan's economy, with exports rising over 70% in August and GDP expected to grow 11% in 2026.
Higher Rates Split Market; AI Stocks Have Advantage: Cramer
Jim Cramer says that rising borrowing costs are splitting the stock market into two camps: credit-sensitive sectors facing pressure and AI-related firms that remain largely insulated. He highlights strong demand for AI growth, citing SpaceX's potential $40 billion borrowing to buy Nvidia chips for data centers, which he expects to get attractive terms despite its BBB rating. In contrast, Skydance's bonds fell after its acquisition of Warner Bros. Discovery, reflecting challenges in traditional media. Cramer argues that AI data center stocks are less affected by Treasury yields because their future growth prospects are considered extremely bright.
