What happened

Western Digital (WDC) surged approximately 7.43% on July 9, 2026, as the memory and storage sector staged a broad reversal after a period of sustained selling pressure.

  • WDC rose more than 7%, with Seagate also climbing around 7% on the same session.
  • Micron and SanDisk each gained approximately 6%, confirming the move was sector-wide rather than company-specific.
  • The rally appears tied to a sentiment shift among investors who had been reducing exposure to memory names.
  • Western Digital has dual exposure to hard disk drives (HDD) and NAND flash storage, making it a broad proxy for data center, enterprise, and consumer storage demand.
