New York, January 14, 2026, 16:35 EST — After-hours
Sandisk Corp (SNDK) shares dipped 0.5% to $387.81 in after-hours trading Wednesday, after earlier swings between $377 and $401. Since its February 2025 debut, the flash-memory maker has skyrocketed nearly tenfold and climbed roughly 65% this year. Retail investors poured a record $7.1 million into the stock on Monday. According to Reuters, it’s also the top holding in the Roundhill Meme Stock ETF. “Seeing Sandisk in the No. 4 slot tells us it is more than a coincidence,” said Steve Sosnick of Interactive Brokers, noting chipmakers are facing what Samsung co-CEO TM Roh described as an “unprecedented” shortage. 1
The timing is crucial since memory is a cyclical segment of semiconductors, and shifts in pricing can quickly upend forecasts. Sandisk, which sells NAND flash memory used in solid-state drives for data centers and consumer devices, sees contract prices rise when supply tightens.
Retail-driven momentum often makes a stock tougher to trade. When positions get crowded, even minor pricing shifts can be amplified, and the window to exit tightens if sellers start flooding the market or buyers pull back.
Bernstein bumped its Sandisk price target sharply, from $300 to $580, and flagged the stock as a top pick for 2026. The firm cited tight NAND supply and steep price hikes as drivers putting Sandisk right in the center of AI-driven data expansion. It called this cycle a “memory and storage supercycle,” highlighting rising demand for larger “key value cache” in AI systems — the short-term storage that speeds up responses — as a major boost for NAND. 2
After splitting from Western Digital, Sandisk launched as an independent public company and started trading on Nasdaq under the ticker SNDK, the company announced. 3

That said, the situation works both ways. Should new capacity come online sooner than anticipated or demand weaken, NAND prices could drop sharply — and the same retail investors who fueled the rally might intensify the sell-off.
Investors are on the lookout for clues that the shortage might be loosening, especially any changes in pricing talk between suppliers and customers. The stock’s wide swings during the day indicate the market is still figuring out the duration of the “tight supply.”
Sandisk plans to release its fiscal second-quarter earnings on Jan. 29, followed by a conference call at 4:30 p.m. EST, per its investor relations page. 5
