DISK is trading at $37.95, up +4.37% as memory-storage shares strengthen after Kioxia and SanDisk extended their Yokkaichi joint-venture agreement through December 2034.
- The extension supports continued NAND manufacturing capacity and supply visibility amid AI-storage demand, providing a sector-specific tailwind.
- Broader markets are slightly lower, suggesting the move is primarily storage-sector driven rather than index-wide.
