Samsung and TSMC fail to excite investors used to torrid AI growth

What happened: Samsung Electronics posted a nearly ninefold rise in quarterly operating profit and TSMC sales jumped 51%, yet investor reaction to the record results was muted. Key numbers: Samsung operating profit up nearly ninefold. TSMC sales up 51%. Samsung stock fell 2.4% Thursday in Seoul. Why it matters: Investors are questioning how long the AI spending boom can last, with big capex plans under pressure from rising borrowing costs worldwide. Suppliers including Tokyo Electron, Advantest and Ibiden declined in Tokyo.
