SanDisk Jumps 14%, Western Digital Climbs 6% as Memory Stocks Rebound on SK Hynix's Capacity Plan - 24/7 Wall St.

The memory sector rebounded as SanDisk and Western Digital shares surged, driven by SK Hynix's announcement to double wafer capacity within five years and triple it by 2034 to meet rising AI-driven de... Read original →

SK Hynix’s aggressive capacity expansion is a structural confirmation of surging AI-driven memory demand, not an isolated move. Its push into 3nm EUV for both NAND and DRAM pressures Micron to accelerate 1β DRAM and 232-layer NAND, while forcing Western Digital and Kioxia (SanDisk’s parent) to rebalance capex between HDDs and QLC NAND—especially as datacenter SSD revenue soars over 600%. Geopolitically, Strait of Hormuz disruptions may not directly hit fabs but could delay Middle East datacenter rollouts, clouding order visibility. Over the next 18 months, winners will be those mastering EUV yield and advanced packaging; second-tier players lacking vertical integration risk being squeezed out by the capex arms race.
