KIOXIA is trading 9.9% down at ¥55,760 as investors reassess exposure to memory-chip names amid mounting concerns over the return on AI infrastructure spending and potential future NAND oversupply.

  • The decline follows a broader tech sell-off triggered by Alphabet’s aggressive AI capex guidance, which has intensified worries that current AI investments may not yield near-term profits.
  • Market pressure is mounting on high-flying semiconductor and AI hardware beneficiaries as investors question the sustainability of massive infrastructure spending.
