NEW YORK, January 4, 2026, 06:44 ET — Market closed
Sandisk Corp shares closed up 15.95% at $275.24 on Friday, leading U.S.-listed storage and memory names into the first session of 2026. U.S. equity markets are closed on Sunday.
The sharp move matters because Sandisk has become a bellwether for investor bets that artificial-intelligence data centers will keep driving demand for storage hardware, after a blockbuster 2025 run for the stock, Barron’s reported. The question now is whether that momentum carries into January as investors reset positioning for the new year. Barron’s
Sandisk said it appointed Alexander R. Bradley, chief financial officer of First Solar, to its board and audit committee, which oversees financial reporting and the company’s outside auditors. “Alex brings exceptional operational finance expertise and strategic insights to Sandisk’s board,” Chief Executive David Goeckeler said; the appointment took effect on Dec. 30, the company said.

Board additions rarely move a stock on their own, but investors often treat them as a signal about governance and capital discipline — an issue that tends to loom large for chip-linked companies that can face sharp swings in demand.
Other storage and memory names also gained in Friday’s session, with Micron Technology up 10.5%, Western Digital rising about 9% and Seagate Technology adding 4.4%, according to market data.
The broader market backdrop was less decisive. U.S. stocks ended mixed on Friday, with Treasury yields climbing and the dollar firming, as investors weighed the rate outlook and the flow of delayed economic data, a Reuters report said. Reuters
For Sandisk, the near-term debate is whether the flash-memory cycle stays tight. Flash memory — often called NAND — is the technology used in solid-state drives and many removable storage products.
A sustained upswing in pricing can lift profits quickly, but the market has a long history of boom-and-bust cycles when supply catches up. Traders are watching for signs that pricing power is peaking, alongside any shift in customer orders tied to data-center buildouts.
Before next session: Sandisk heads into Monday’s open after a breakout move that could draw both momentum buying and profit-taking. Some traders will focus on whether the stock holds above Friday’s close and how it behaves around round-number levels that often act as psychological “speed bumps.”
Sandisk has said it will report fiscal second-quarter results on Jan. 29 and host an earnings conference call at 1:30 p.m. Pacific time (4:30 p.m. ET). Investors will look for updates on revenue, margins and earnings per share — profit divided by the number of shares — and any guidance that frames demand and pricing into the spring. Business Wire
Macro catalysts are also lining up. The U.S. Labor Department’s Employment Situation report for December is scheduled for Jan. 9, a release that can move bond yields and swing sentiment toward high-valuation technology shares. Bureau of Labor Statistics
