New York, January 5, 2026, 10:51 (EST) — Regular session
Sandisk Corp shares rose 1.4% to $279.00 in morning trading on Monday, as investors returned to memory and storage names tied to artificial intelligence data-center spending. The stock has traded between $266.73 and $288.95, with about 4.8 million shares changing hands.
The move matters because memory chips sit at the heart of the AI buildout, and tight supply typically translates into higher contract prices and fatter margins for suppliers. Traders have been buying the group on the view that data-center demand is absorbing capacity faster than manufacturers can add it.
Sandisk sells NAND flash — a type of non-volatile memory used in solid-state drives and removable storage such as USB drives and memory cards — leaving its earnings particularly sensitive to swings in flash pricing. The company also supplies storage products across cloud, client and consumer markets. Reuters
The rally comes as chipmakers pivot capacity toward high-bandwidth memory, or HBM, a specialized product used alongside AI accelerators in servers, crimping supply elsewhere. Samsung co-CEO TM Roh called the shortage “unprecedented” in an interview with Reuters, and market-research firm TrendForce said prices in some segments have more than doubled since February 2025. Analysts at Morningstar and J.P. Morgan have estimated the upturn — often dubbed a “supercycle” — could persist into 2027. Reuters
Other stocks in the space were mixed but mostly higher. Micron Technology rose about 1% and the iShares Semiconductor ETF gained about 2.5%, while Western Digital added about 1.3%, Applied Digital jumped about 6.6% and Seagate was little changed.
For Sandisk, traders are watching whether the stock can hold above its prior close near $275 and revisit Monday’s intraday high just below $289. The group has shown sharp day-to-day swings as investors debate how long tight supply can last.
But the memory business is notoriously cyclical, and a faster supply response or a pause in cloud spending would pressure flash prices. Any sign that the AI capex cycle is cooling, or that new capacity is arriving quicker than expected, would test the market’s “supercycle” narrative.
The next company-specific catalyst is Sandisk’s fiscal second-quarter results, with an earnings conference call scheduled for Jan. 29 at 1:30 p.m. Pacific time (4:30 p.m. Eastern). Investors will be looking for management’s read on NAND pricing, capacity plans and data-center demand. Businesswire
