WSJ Report Sends Memory Stocks Down. SanDisk Down 9%, Micron Down 7%, Western Digital Down 5%

The report, cited by Yahoo Finance, triggered a broad selloff across memory names on August 18. SanDisk fell 9%, Micron declined 7%, and Western Digital dropped 5%, according to the headline; the summary provided no further details on the WSJ report.

Western Digital enters the move with FY 2026 revenue of $12.9B, up 35.7% year over year, based on SEC EDGAR data for the fiscal year ended July 3, 2026. Its reported gross margin was 48.9%, net margin was 72.9%, and diluted EPS was $24.28.

The immediate read-through is sector-wide rather than company-specific, with WDC grouped alongside SanDisk and Micron in the market reaction. The key unresolved issue is what the WSJ report said about memory demand, pricing, supply, or industry exposure; without that detail, the durability of the selloff cannot be established from the supplied information alone.
