WDC is trading 8.4% down today at $670.97 as momentum unwinds following an extended run-up driven by AI storage optimism.
- The stock had gained over 50% in the last 30 days and approximately 290% year-to-date, leaving it trading on a rich valuation multiple and vulnerable to a pullback.
- With the broader tech sector under pressure and no fresh company-specific headlines, the move appears to be a sector-led correction and momentum unwind.
