WDC Stock Surges 10% in a Single Day — And Earnings Season Hasn’t Even Started Yet

Western Digital has been headquartered in a building on Bering Drive in San Jose, California, over the course of more than 50 years of technological change, including the shift from floppy disks to hard drives, from spinning platters to flash memory, the dot-com bubble, the 2008 financial crisis, and the pandemic supply chain chaos that upended every manufacturer worldwide. The business has persevered through it all, sometimes just barely. Then, early in 2025, something changed. The price of the stock was close to $28. It reached $319 by March 2026. That isn’t healing. That is a separate business with the same name.

The headline story is told by the one-year return of 631 percent, but it’s the details that make Western Digital truly fascinating to watch at this time. Revenue of $3.02 billion, up 25% year over year, and an EPS of $2.13, exceeding the $1.93 estimate by more than 10%, were reported in the Q2 fiscal 2026 results. The gross margin was 42.7%. The return on equity was 41%. These figures call for a reevaluation of the narrative for a company that, just eighteen months ago, was being written off in some quarters as a legacy storage company under existential pressure from cloud-native competitors.

On April 2, 2026, Bernstein upgraded Western Digital from Market Perform to Outperform and increased its price target to $340, citing strong demand for AI-driven data center storage as the main driver of the 10% one-day spike. It was a wise choice of timing. WDC had dropped 7.5 percent in a single day just two sessions prior as investors were concerned about how the escalating Iranian conflict might affect semiconductor supply chains, particularly the availability of specialized manufacturing gases like helium that are necessary for chip production. Western Digital uses facilities that rely on those supply chains to manufacture its NAND flash memory. The fear was genuine enough. However, it appears that Bernstein believed the selloff had exceeded the real risk, and the market reacted appropriately.

The implications of the impending earnings call are worth considering. Wall Street is expecting Western Digital to report fiscal Q3 2026 revenue of approximately $3.2 billion — a 40 percent increase from the $2.29 billion recorded in the same quarter a year ago. Gross margin guidance is targeted between 47 and 48 percent, which would be a meaningful sequential improvement. The estimated diluted EPS is $2.30. If those numbers land anywhere near expectations, it will be one of the company’s strongest quarterly performances in recent memory. Management has already guided for over $20 EPS on a multi-year basis, a figure that, if achieved, would look extraordinary against the current price. The April 30 earnings call is, for investors paying attention, the next major event on the calendar.

The stock has now gained roughly 73 percent year-to-date in 2026, placing it among the strongest performers in the entire technology sector. Twenty-one of twenty-five brokerage firms that cover it have assigned a Strong Buy rating. The average brokerage recommendation sits at 1.28 on a scale of 1 to 5, which is very close to the maximum bullish reading. It’s possible, of course, that analyst enthusiasm is running slightly ahead of reality — brokerage firms have well-documented incentives to rate stocks favorably, and consensus buy ratings during momentum periods have historically been a less reliable signal than the numbers themselves. The more grounded view comes from Zacks, which currently rates WDC as a Hold based on earnings estimate revision trends, suggesting that while the business is performing well, the near-term price performance may already reflect much of what is known.

There’s a feeling, watching Western Digital’s trajectory over the past year, that the company benefited from several things arriving simultaneously: the AI infrastructure buildout creating genuine demand for high-capacity nearline storage in data centers, the NAND flash market moving into a supply-demand balance that supports pricing, and management executing on margin improvement at exactly the moment the macro tailwinds appeared. The company also has a collaboration with Microsoft on an HDD recycling pilot that recovers rare earth materials from decommissioned drives — a smaller story, but one that speaks to how the company is thinking about its supply chain over the longer term.

Storage isn’t very glamorous. It doesn’t attract the same intense interest as cloud platforms or AI chip manufacturers. However, data must have a home, and the amount of data generated and needed by AI systems is increasing at a rate that even the most optimistic projections from three years ago were unable to predict. Western Digital’s stock price is genuinely reflecting that reality more than any analyst upgrade or geopolitical upswing.
