NEW YORK, Jan 3, 2026, 10:10 ET — Market closed
- Sandisk shares closed up 15.95% on Friday at $275.24, ending near the session high
- The flash-storage maker named First Solar CFO Alexander R. Bradley to its board and audit committee
- Investors are looking ahead to Sandisk’s next earnings call and a busy U.S. data slate next week
Sandisk Corp shares closed up 15.95% on Friday, finishing at $275.24 in the first U.S. session of 2026.
The surge matters because Sandisk has become a high-momentum proxy for the “memory trade” — bets that demand for storage tied to AI data centers is tightening supply and lifting pricing for flash products. The stock ended 2025 up sharply from its $36 spin-off price after separating from Western Digital, Barron’s reported. Barron’s
It also comes as investors started the year leaning into chip-linked names even as broader indexes were mixed, with the Philadelphia SE Semiconductor index up about 4% on Friday. The macro backdrop is still in focus, with Treasury yields rising as markets looked ahead to next week’s labor-market data.
Sandisk opened Friday at $244.35, traded as high as $275.80 and as low as $244.00, and saw about 11.1 million shares change hands, according to Yahoo Finance data.
Storage and memory peers also drew bids. Western Digital rose about 9% and Micron gained about 11% in the same session, Barron’s reported, underscoring the sector-wide tone.
Late Friday, Sandisk said Alexander R. Bradley — the chief financial officer of First Solar — joined its board of directors and was appointed to the audit committee. The appointment was effective Dec. 30, 2025, and brings Sandisk’s board to eight directors, seven of them independent, the company said.
“Alex brings exceptional operational finance expertise and strategic insights to Sandisk’s board,” David Goeckeler, Sandisk’s chairman and chief executive officer, said in the statement. Business Wire
A securities filing cited by Investing.com said the company did not have any arrangements or understandings with other parties regarding Bradley’s appointment, and said he had no material interest in transactions requiring disclosure under SEC rules.
Sandisk develops and sells data-storage products built on NAND flash — a type of non-volatile memory widely used in solid-state drives (SSDs) and removable storage — serving cloud, client and consumer markets, according to a Reuters company profile.
Before the market reopens on Monday, traders will be watching whether Friday’s move gets follow-through, and whether Sandisk’s next update offers new detail on pricing and demand for enterprise SSDs — a key data-center product category for the company and its competitors. Sandisk has scheduled its fiscal second-quarter earnings conference call for Jan. 29.
Macro risks are also on the radar for high-beta chip and hardware names. The U.S. ISM services report is due Jan. 7, and the government’s monthly employment report is scheduled for Jan. 9, according to published calendars; either can move rate expectations that feed directly into tech valuations.
On the chart, Friday’s wide range puts the prior close around $237 and the $244 intraday low in focus as nearby reference points, while the $275.80 session high marks the next level bulls will try to defend.
