NEW YORK, January 3, 2026, 03:48 ET — Market closed
Sandisk Corp shares jumped 15.9% on Friday to close at $275.24, after trading as high as $278.78 and as low as $242.00 in the first U.S. session of 2026. About 11.1 million shares changed hands.
The move matters because Sandisk has become a high-beta way to play data-center spending, where flash-based solid-state drives are used to feed AI servers fast data. Barron’s noted the stock’s strong 2025 run after its Western Digital spin-off, keeping it on momentum screens heading into the new year. 1
Other storage and memory names rose with it on Friday. Micron gained 10.5%, while former parent Western Digital rose 9% and Seagate added 4.4%, underscoring a broader bid in the space rather than a single-stock move.
Sandisk also announced a board change, naming First Solar CFO Alexander R. Bradley as a director and adding him to its audit committee, effective Dec. 30. “Alex brings exceptional operational finance expertise and strategic insights to Sandisk’s board,” Chairman and CEO David Goeckeler said. The audit committee oversees financial reporting and the company’s relationship with its outside auditor. 2
Sandisk develops data storage products based on NAND flash, a type of memory used in devices from consumer gadgets to data centers. Its portfolio includes solid-state drives, which store data without spinning disks, as well as removable cards and USB drives, Reuters data showed. 3
The company returned to the public markets in February 2025 after completing its separation from Western Digital and began trading on Nasdaq under the ticker “SNDK,” Sandisk said at the time. 4
Broader markets were mixed in Friday’s session. The SPDR S&P 500 ETF Trust rose 0.2%, while the Invesco QQQ Trust, which tracks the Nasdaq 100, slipped 0.2%.
Before Monday’s open, traders will look to the next company milestone: Sandisk is scheduled to hold its fiscal second-quarter earnings conference call on Jan. 29. The call is set for 1:30 p.m. Pacific time (4:30 p.m. ET). 5
That report is expected to refocus attention on two variables that have driven the stock’s swings: the direction of NAND pricing and the mix shift toward higher-margin enterprise storage, versus consumer products that can turn quickly with the cycle.
Macro data could also move the goalposts for tech valuations. The U.S. Employment Situation report is due Jan. 9, followed by the Consumer Price Index on Jan. 13, according to the Bureau of Labor Statistics schedule. 6
After Friday’s wide range, short-term traders are watching whether the stock can hold above the $275 area and revisit the session high near $279 without another sharp reversal.
