Major technology and software firms reported robust quarterly results, with Nvidia leading a market surge fueled by accelerating artificial intelligence investment. While investor enthusiasm remains high, some financial analysts caution that valuation pressures and shifting demand patterns warrant careful monitoring.

Nvidia reported stronger-than-expected quarterly results and signaled sustained growth in artificial intelligence infrastructure spending, triggering a premarket rally across technology and cybersecurity stocks. The upbeat outlook eased investor concerns about an AI investment bubble while driving gains for major chipmakers and software providers.

South Korean technology stocks, particularly chip manufacturers, experienced significant declines amid growing skepticism about the AI market and an extended chip rout. SK Hynix shares were notably affected, deepening their decline due to an earnings miss, excessive leverage by retail investors, and fears of Chinese competition.
