WDC fell 10.2% to $415.29
Western Digital fell 13.03% on August 6, from $519.17 to $451.52, despite fiscal Q4 2026 results released after the close on August 5 that beat on both lines: revenue of $3.75 billion, up 44% year over year against roughly $3.69 billion consensus, and non-GAAP diluted EPS of $3.56 versus about $3.31. The decline reflected an unusually high expectations bar — the stock had gained roughly 201% year to date into the print, having tripled in 2026 — together with less favourable comparisons against Seagate, a same-day Summit Insights downgrade from Buy to Hold, and a broader de-rating across storage and memory names.
