NEW YORK, January 6, 2026, 11:34 (ET) — Regular session
- SNDK rose about 22% in morning trading and hit $343, a 52-week high.
- Sandisk rolled out “Sandisk Optimus” branding for its internal solid-state drive lineup at CES 2026.
- TrendForce expects NAND flash contract prices to rise 33%–38% in the first quarter.
Sandisk Corp shares jumped more than 22% on Tuesday. The Nasdaq-listed stock was up 22.1% at $334.75 by 11:05 a.m. ET, after touching $343 and trading about 12.9 million shares, StockAnalysis.com data showed. 1
The rally puts Sandisk back in the spotlight as investors chase memory-linked names on expectations that tight supply will push up prices for chips and storage drives this quarter. TrendForce forecast conventional DRAM — the working-memory chips used in servers and PCs — contract prices to rise 55%–60% in the first quarter, and said NAND flash — used in solid-state drives — could climb 33%–38%. 2
The company late Monday unveiled “Sandisk Optimus” as the new name for its internal solid-state drive lineup at CES 2026, rebranding products previously sold under WD_BLACK and WD Blue labels. “The SANDISK Optimus™ brand redefines what performance means for consumer needs,” marketing vice president Heidi Arkinstall said, while product chief Anil Moolchandani said the new name matches a portfolio that “millions of people around the world” already trust. Sandisk said products with the updated branding are expected to reach select retailers worldwide in the first half of 2026. 3
Memory stocks have rallied this week on bets that demand for artificial-intelligence infrastructure is draining supply, with chipmakers shifting capacity toward high-bandwidth memory, or HBM, used in AI servers. Samsung co-CEO TM Roh called the shortage “unprecedented” and Micron CEO Sanjay Mehrotra has said he expects memory markets to stay tight past 2026; Micron and former parent Western Digital climbed on Monday, Reuters reported.
Sandisk completed its separation from Western Digital in February 2025 and began trading on Nasdaq under the ticker SNDK, the company said. It sells flash-based storage and memory technology used in data centers, PCs and consumer devices. 4
But flash is a cycle business, and prices can turn quickly if cloud customers slow orders or chip supply loosens. The CES branding change also does little, on its own, to settle questions about demand and valuation.
