New York, Feb 24, 2026, 10:01 EST — Regular session
- Sandisk shares climbed early, even as Citron Research revealed it was shorting the stock.
- Citron pointed to competitive threats, cautioning that what’s being called a NAND “shortage” might disappear just as fast.
- Investors eye Sandisk’s conference lineup kicking off Feb. 25.
Sandisk Corp shares climbed Tuesday, even as a short-seller took a swing at the rally—raising the question of whether buyers would stick around once things got complicated.
Shares moved up roughly 1.3% to $675.19 as of 9:47 a.m. ET.
Sandisk’s rapid ascent in recent months makes this move significant—momentum stocks like this often swing sharply when a high-profile short-seller such as Citron jumps in. Citron’s call also comes right as investors are wrestling with the question of just how long the current memory upcycle holds up before extra supply enters the mix.
Citron Research is betting against Sandisk, calling out what it sees as misplaced scarcity hype in the stock, despite growing competition. The firm shot off a note: “This ‘shortage’ is a supply mirage that can vanish in a single earnings call.” Investing.com
Shares slid roughly 1% following Citron’s post, but reversed course and moved up, Investing.com reported.
Citron flagged Samsung as a potential threat, warning that the market cycle can shift quickly if a major player decides to chase market share instead of profits. “Samsung is already the 800-pound gorilla,” Citron said. Investing.com
Sandisk, headquartered in Milpitas, California, makes flash memory storage built on NAND chips—the same kind found in solid-state drives and similar products. After a spinoff from Western Digital in February 2025, the company kicked off life as an independent public firm, according to a prospectus filing.
Western Digital has been trimming its leftover holding in Sandisk, as it shifts its focus back to hard drives, Reuters reported last week. Traders in Sandisk have kept an eye on that overhang from share sales—it’s been a nagging issue.
At the heart of the conversation: durability. Memory has always been a boom-bust business, lurching from scarcity to oversupply. Despite the recent surge in AI-fueled demand that’s been driving prices higher, analysts keep sounding the alarm about another possible glut.
Sandisk closed out Monday at $666.49, Zacks data show.
Still, things could head south even without a recession. Should NAND supply accelerate beyond forecasts, or if Samsung pushes more aggressively on volume, prices might weaken and the stock’s multiple could shrink in a hurry. That’s the angle Citron is playing.
All eyes shift to Sandisk executives’ public remarks now. The stock’s been moving lately on sector chatter rather than anything new out of the company itself.
Sandisk plans to take the stage at the Bernstein “What’s Next in Tech?” forum on Feb. 25, then heads to the Morgan Stanley Technology, Media & Telecom Conference set for March 3. After that, another appearance is lined up for March 11. The schedule comes from a company release posted by Barchart. barchart.com
