Western Digital Corp’s shares climbed 16.8% to $219.38 in after-hours trading on Tuesday. The stock reached $221.16 earlier in the session.
The rally occurred after CEO Jensen Huang spoke at CES in Las Vegas. He unveiled a next-generation chip platform named Vera Rubin.
Huang also introduced a storage technology he termed “context memory storage.” This feature is aimed at enabling AI chatbots to handle long questions and conversations more expeditiously.
Western Digital manufactures hard disk drives for cloud, client, and consumer markets. Investors have utilized the stock as a means to capitalize on AI infrastructure spending.
The company’s cloud business serves public and private cloud environments. It also sells directly to end customers.
Storage Sector Ignites
Tuesday’s movement was not confined to Western Digital. SanDisk jumped by over 27% in the same session.
Seagate Technology gained 14%. rose 10%.
All four stocks hit record highs, as per Reuters. “I believe we are going to have a very robust earnings season for Big Tech,” stated Jed Ellerbroek, a portfolio manager at Argent Capital.
Ellerbroek anticipates that capital spending estimates will increase once more. This view mirrors broader optimism regarding AI data center expansions.
SanDisk employed CES to rebrand its internal NVMe solid-state drives. The new series is called SanDisk Optimus.
The top GX PRO tier is targeted at developers, professionals, and gamers constructing AI PCs and workstations. The company plans to roll out the updated branding to select retailers in the first half of 2026.
Recent Guidance and Separation
Western Digital’s most recent guidance dates back to October. CEO Irving Tan stated that the firm was performing well in a “strong demand environment propelled by the growth of data storage in the cloud.”
CFO Kris Sennesael projected that fiscal second-quarter revenue would be approximately $2.9 billion at the midpoint. He also guided for non-GAAP EPS of roughly $1.88.
The company completed the separation of its flash unit into SanDisk on February 21, 2025. That split provided investors with two pure-play names in the storage market.
However, rapid price increases leave less room for error if demand weakens. Morningstar analyst William Kerwin said Nvidia’s storage platform “would add more SSD storage to AI infrastructure to enhance model speed.”
He cautioned that current high prices may not be sustainable over the long term. This caution reflects concerns about valuations stretched by rapidly changing sentiment.
Traders will now monitor U.S. labor market data for the next catalyst. The Bureau of Labor Statistics will release the Job Openings and Labor Turnover Survey on Wednesday, January 7.
The December Employment Situation report follows on Friday, January 9. Both reports can shift rate expectations and influence high-multiple tech trades such as Western Digital.
