🟢 DISK is trading 3.2% up in pre-market as memory and NAND stocks rally

DISK is trading 3.19% up at $40.48 after broad strength across memory and NAND-related stocks.

• Its portfolio includes major memory companies such as SanDisk, Kioxia, SK hynix, and Micron, providing direct exposure to the sector’s rally.
• SanDisk peers also advanced sharply, with coverage describing the move as a cycle bid rather than a single-company squeeze.
• No fresh DISK-specific announcement, earnings release, or filing was identified for September 8, 2026; the ETF is therefore most likely following memory-sector momentum rather than a company-specific catalyst.
