New York, January 13, 2026, 17:38 EST — After-hours trading
- Sandisk shares hit a new peak of $398 before settling just 0.1% higher at $389.81
- Investors are zeroing in on signals of constrained NAND supply and rising SSD prices driven by AI data-center demand
- Sandisk’s fiscal second-quarter earnings, set for Jan. 29, stand as the next key catalyst
Shares of Sandisk Corp climbed to a new peak on Tuesday, touching $398.00 before slipping back to close up just 0.1% at $389.81.
Shares have surged roughly 63% so far this year, making the stock one of the strongest momentum plays. Sandisk went independent and started trading on Nasdaq in early 2025, following its split from Western Digital.
The speed is crucial now as the coming weeks will test if pricing and margins truly keep up with the stock’s rapid climb. Much of the buying bets on flash memory tightening right alongside the surge in AI infrastructure.
The wider market slipped on Tuesday, dragged down by financial shares falling over concerns about a proposed cap on credit-card interest rates. Inflation data also weighed on sentiment. “Financials are getting hit by Trump’s credit-card proposal,” noted Tim Ghriskey, senior portfolio strategist at Ingalls & Snyder. Reuters
Sandisk’s bullish outlook depends on NAND flash—the memory chips used in solid-state drives and countless consumer gadgets—shifting into a sellers’ market. TrendForce predicted earlier this month that NAND flash contract prices might jump 33%–38% in the March quarter compared to the previous one, while client SSD prices are set to increase by at least 40%.
Another driver of the buzz: talk of bigger hikes at the top tier. Nomura Securities, in a client note highlighted by Tom’s Hardware, said Sandisk might sharply increase prices on high-capacity 3D NAND chips for enterprise SSDs — the kind used in data centers — as hyperscalers ramp up orders linked to AI workloads.
Sandisk is gearing up to release its fiscal second-quarter results on Jan. 29, with a conference call planned for later that day.
The group showed a split picture, underscoring the continued volatility in this crowded sector. Western Digital nudged up 0.9%, but Seagate dropped 1.0% and Micron lost 2.2%.
Memory markets carry a clear risk: they move in cycles. If supply shows signs of easing or AI-driven demand isn’t as intense as buyers expect, prices could tumble fast — and momentum stocks rarely stick around to see what happens next. Reuters notes the current memory rally is driven by an AI-related supply squeeze, but the sector’s typical boom-and-bust pattern remains a looming threat.
All eyes are on Jan. 29 for clues on pricing, demand from major cloud clients, and how much margin improvement actually materializes — along with any signals about whether the rally might be outpacing the fundamentals.
