NEW YORK, January 3, 2026, 04:36 ET — Market closed.
- Western Digital closed up 8.96% on Friday at $187.70 after a wide intraday swing.
- Storage and memory peers also advanced, keeping the “AI infrastructure” trade in focus.
- Next week’s U.S. jobs report and inflation data are the next big tests for risk appetite.
Western Digital Corp shares ended Friday up 8.96% at $187.70, after trading between $176.00 and $188.90.
The move underscored investors’ early-year appetite for “AI infrastructure” stocks — companies that supply the hardware needed to build and run artificial intelligence systems. “Value is outperforming growth and AI infrastructure is up,” said Jed Ellerbroek, portfolio manager at Argent Capital in St. Louis. 1
Other data-storage and memory names moved in tandem, with Micron Technology up 10.51%, Seagate Technology up 4.40% and Sandisk up 15.96% on the day.
Western Digital has been repositioning itself as a more focused hard-drive company after completing the separation of its flash business into Sandisk in February 2025. 2
The company sells high-capacity hard disk drives used in cloud data centers, often referred to as “nearline” drives — storage built for always-on servers, not personal computers. Investors have leaned on the view that AI systems generate and keep far more data, lifting demand for storage alongside compute.
Western Digital’s last major update in October included a forecast for second-quarter earnings above Wall Street estimates, as it pointed to rising cloud storage demand tied to expanding data center capacity. 3
Friday’s rally left traders watching whether the stock can hold recent gains without fresh company-specific headlines, as rates and macro data steer risk sentiment across tech-adjacent sectors.
Before the next session, attention turns to U.S. employment data due Jan. 9 and the consumer price index report due Jan. 13, as investors look for signals on the path of Federal Reserve rate cuts. Fourth-quarter earnings season also ramps up, with major U.S. banks due to report starting Jan. 13. 4
For Western Digital, the next clear company catalyst is its next quarterly report; the company has not confirmed a date, while Nasdaq’s earnings calendar currently lists an estimate of Feb. 4, 2026. 5
Investors will also measure results against the company’s most recent outlook, which called for fiscal second-quarter revenue of about $2.9 billion, plus or minus $100 million, with non-GAAP gross margin in the 44%–45% range. 6
On the charts, $190 is the next resistance — a level where selling pressure often appears — after Friday’s surge. The day’s low near $176 marks the first support, where buyers stepped in during the session.
