Why Is WESTERN DIGITAL CORP (WDC) Stock Up Today?

By the Top Tier Newswire AI Desk · July 22, 2026 at 12:05 AM ET · reviewed against 7 wire stories

WESTERN DIGITAL CORP (WDC) is up +12.51% in the latest session. Our newswire has captured 7 stories on WDC across 6 sources in the last 36 hours, with AI sentiment reading bullish (avg 59/100).

Western Digital Corp (WDC) surged 12.51% to $548.39 on Tuesday as part of a broader rebound in the memory and storage sector. The stock joined SanDisk and Micron in rising for a second consecutive session amid renewed optimism about the sector's outlook. The move coincided with a Bank of America upgrade and a broad UBS report that reinforced confidence in the sector's recovery.

What Happened

WDC's sharp rise came after weeks of intense selling driven by concerns that hyperscalers would scale back AI investments. The recent rebound has been fueled by expectations that demand for memory and storage will remain strong despite earlier fears of a slowdown. WDC's stock was among the top three gainers in the S&P 500 on Tuesday, reflecting the broader trend. The rally also coincided with one of the busiest earnings weeks of the summer, as investors look for confirmation of the sector's strength.

What The Data Shows

Over the last eight sessions, WDC fell 4.1% from $573.98 to $550.20, but the recent rebound has reversed that trend. The stock is now trading within a range of $503 to $598 as of July 21, 2026, which is being closely watched by traders for potential options strategies. Insiders have sold $9.8 million in shares over the last 90 days, with the most recent sale occurring on July 21. Meanwhile, Donald J. Trump has made three separate purchases of WDC between March 2 and March 23, 2026, each in the range of $15,001 to $50,000.

What To Watch

Western Digital is not scheduled to report earnings in the near term, but investors will continue to monitor the broader memory sector for signs of sustained momentum. The coverage breadth remains strong, with seven stories published in the last 36 hours, and the stock's performance could be influenced by the next round of earnings from key players in the space.
