On September 18, Western Digital rose 3.11% in regular trading, trading at $436.49/share, with turnover of $380 million, extending gains for a third consecutive session as the storage sector maintained upward momentum.

The rally is underpinned by a persistent global memory supply-demand imbalance. Delivery cycles for key semiconductor manufacturing equipment components in South Korea have more than doubled, further tightening the supply side. Citi projects global memory capital expenditure to surge 46.5% year-over-year to $80.4 billion by 2027, yet the prolonged lead times for capacity buildout mean that even massive investment is unlikely to close the supply-demand gap in the near term. Additionally, HBM capacity constraints and slower technology migration have caused expansion to lag significantly behind surging demand, particularly from the server segment. Data from CFM Flash Market showed Q2 global DRAM market revenue hit a record $147 billion, up 55.9% quarter-over-quarter.

Within the Technology Hardware, Storage & Peripherals sector, Seagate Technology rose 3.16%, SanDisk Corp. rose 2.11%, while Apple slipped 0.02%, Dell Technologies fell 0.14%, and Super Micro Computer declined 2.28%.
