On August 19, Western Digital fell 3.12% in regular trading, trading at $479.51/share, with turnover of $692 million. The decline extends the sector-wide profit-taking pattern that followed the sharp rally on August 17, when the stock surged over 6% on bullish comments from Elon Musk and Goldman Sachs demand forecasts for AI-driven storage.

The storage chip sector continued to face broad selling pressure despite pre-market gains earlier in the session. Within the Technology Hardware, Storage & Peripherals sector, peer stocks declined in tandem: Dell Technologies fell 6.4%, Seagate Technology fell 3.34%, Super Micro Computer fell 2.38%, and SanDisk fell 2.34%. Bernstein's forecast that Q3 DRAM and NAND contract price increases will narrow to approximately 20%, along with its view that the storage pricing upcycle may be approaching its end, continued to weigh on sector sentiment. Multiple investment banks have recently raised target prices for Western Digital — Bernstein to $770, Morgan Stanley to $676, and BNP Paribas to $700 — though near-term momentum remains constrained by valuation recalibration following the prior session's gains.
