SanDisk is trading at $8.08, down 11.40%, amid a memory-chip selloff. - Lingering concern about Chinese rival CXMT’s progress on denser memory designs and plans for server-memory products has weighed on memory shares; CXMT’s announced product is DRAM, not SanDisk’s flash storage. - Hotter-than-expected September inflation revived rate-hike concerns, pressuring technology stocks. - No new company-specific catalyst explaining the October 15 move was identified.
