Why Kioxia (KIOXIA) fell 7.53%
Kioxia (KIOXIA) fell 7.53% on August 7, 2026 — SanDisk, Western Digital earnings sink AI Memory.
What happened
Memory stocks across the AI Memory theme fell sharply as SanDisk and Western Digital missed earnings guidance, signaling weakening demand for memory chips after months of AI-driven shortage premiums.

What would break the thesis
