BlockBeats News, July 22nd. The AI industry chain frenzy has heated up again, and the chip sector in the Japanese and South Korean stock markets surged significantly today. South Korean semiconductor giant SK Hynix rose more than 9% at one point, Samsung Electronics rose more than 6% at one point, driving the South Korean KOSPI index to rise by over 6% intraday. Subsequently, the South Korean exchange activated the Sidecar mechanism, pausing programmatic buying of KOSPI.

The Japanese stock market also strengthened simultaneously, with the Nikkei 225 Index rising by about 1.7%, led by chip stocks. Among them, Kyaxa's stock price surged over 8%, Rohm Semiconductor surged over 4%, and SoftBank Group surged over 3%.

Intel and AMD rose over 8%, Arm rose over 7%, TSMC ADR rose over 5%; storage concept stocks performed strongly, with SanDisk surging over 14%, SK Hynix ADR rising over 13%, Micron Technology and Western Digital rising over 12%.

Market analysis believes that the AI capital expenditure cycle is not over yet, with strong demand still present for data center construction, computing power, storage, and network infrastructure. The recent improvement in Asian export data, as well as pricing actions by manufacturers such as TSMC, further strengthen market confidence in the demand for the AI industry chain.
