On August 18, Western Digital fell 5.32% in regular trading, trading at $508.16/share, with turnover of $552 million. The storage chip sector faced broad selling pressure as investors locked in gains from the prior session's rally, during which Western Digital surged over 6% and SanDisk climbed over 8%, catalyzed by Elon Musk's bullish comments on storage as a core constraint for autonomous AI and Goldman Sachs raising demand forecasts.

The profit-taking was compounded by Bernstein's projection that Q3 DRAM and NAND contract price increases will narrow to approximately 20%, suggesting the storage pricing upcycle may be approaching its tail end. Within the Technology Hardware, Storage & Peripherals sector, SanDisk fell 5.01%, Seagate Technology fell 4.95%, Super Micro Computer fell 1.27%, while Apple rose 0.39% and Dell Technologies rose 1.61%.
