Semiconductor stocks, led by Kioxia and others, declined as SK hynix's plunge in South Korea and concerns over AI-related debt weighed on market sentiment. In the market on the 20th, SK hynix fell into the six-month low range.
Semiconductor stocks, including major memory chipmakers, are being sold, with Kioxia Holdings and SoftBank Group among the names to decline.
SK hynix's sharp share-price decline reflects shareholder concerns over the dual-listing issue involving its US subsidiary Solidigm, as well as expectations of weaker supply-demand conditions following the end of its share buyback program. Although no earnings announcement is scheduled for the 30th, the company is due to report third-quarter results on the 28th.
Expectations are emerging that China's CXMT will report a substantial year-on-year increase in sales for the July-September quarter, raising concerns about future oversupply and margin declines resulting from intensifying competition.
S&P Global said that major technology companies worldwide are likely to carry potential AI-related debt that cannot be fully identified externally, even as their data-center investments continue. In Tokyo trading on the 20th, Kioxia fell ¥605 from the previous day to ¥12,995, while SoftBank Group dropped ¥311 to ¥4,524.
