According to CoinMeta, Asian tech stocks tumbled significantly due to concerns about the sustainability of spending related to artificial intelligence, affecting both the Nikkei index and South Korea's KOSPI index. The stock prices of SoftBank, Tokyo Electron, and Advantest fell sharply, and Samsung Electronics and SK Hynix also experienced significant declines, reflecting investors' anxiety regarding large-scale AI capital expenditures. Although the overall decline in Japan's TOPIX index was relatively mild, the Nikkei index's heavy drop indicates that selling pressure was mainly concentrated on stocks related to AI and semiconductors. The decline in the South Korean market was sufficient to trigger the seller's circuit breaker mechanism, highlighting the particular stress in the semiconductor industry.
