On October 13, Western Digital fell 6.79% in Regular Trading, trading at $363.06 per share, with turnover of $439.0 million.
The move came as memory and storage names stayed broadly weak after fresh reports pointed to intensified competitive pressure from CXMT's 4F² architecture breakthrough, while investors also reassessed whether strong memory fundamentals may be closer to a cyclical peak than previously assumed.
Recent market coverage showed Western Digital already under pressure in earlier trading as memory peers including SK Hynix, Micron, Seagate and SanDisk declined. Additional background indicated concerns around Toshiba capacity expansion and repeated long-dated synthetic bearish options positioning in Western Digital, including structures tied to selling $520 calls and buying $300 puts for January 2027, which further weighed on risk appetite ahead of the company's October 22 earnings report.
