New York, Feb 25, 2026, 16:01 (EST) — After hours trading now underway.
- Sandisk finished Wednesday’s session 0.3% higher, bouncing back a bit after dropping 4.2% the previous day on a Citron Research short call.
- Sandisk execs are set to appear at the Bernstein forum tonight, with investors tuning in. Nvidia is also reporting after the U.S. closing bell.
- CFO Luis Felipe Visoso sold shares, according to a new Form 4, to cover tax withholding from vesting awards.
Sandisk Corp ended Wednesday up 0.3% at $640.51, with shares bouncing from $624.53 to $661.19. Traders juggled a new short call alongside a flood of tech catalysts heading into the close.
Sandisk, now seen as a stand-in for the AI-driven memory space, is once again showing volatility right before Nvidia reports results after the U.S. close. Tech stocks climbed globally, lifting shares and pushing the Nasdaq into positive territory for the session, according to Reuters.
Sandisk grabs some attention this evening. The company heads to the Bernstein Insights: What’s Next in Tech? event at 6:30 p.m. ET. KC Rajkumar of Lynx Equity Strategies expects execs to address the NAND flash shortage, plus ongoing talks with major cloud clients about locking in multi-year, non-cancellable supply deals — the kind that prevent buyers from backing out each quarter.
On Tuesday, Citron Research revealed it’s shorting Sandisk, contending the market’s pricing treats Sandisk “like NVIDIA”—a comparison Citron disputes since, in their words, the company is in the commodity business and could be hit by a sharper supply push from Samsung. “NVIDIA has a moat. SanDisk sells a commodity,” the note read, as reported by Investing.com. Investing.com
Sandisk’s EVP and CFO, Luis Felipe Visoso, sold 1,594 shares at $649.97 each in a tax-withholding deal linked to vesting, according to a Form 4 filed Feb. 24. After this transaction, Visoso reported owning 166,646 shares.
Supply from shareholders hasn’t gone away, either. Earlier this month, Western Digital—Sandisk’s former parent—announced plans to unload $3.17 billion worth of shares. According to Reuters, the deal would see roughly 5.8 million shares swapped to affiliates of J.P. Morgan and BofA in exchange for debt, trimming Western Digital’s holding down to about 1.7 million shares.
Bulls face a big risk if the “shortage” story unravels quickly. Andrew Left of Citron sounded the alarm in an X post, writing, “Memory is a cycle, and cycles peak.” He pointed to Samsung’s production limits, telling Business Insider those constraints come with an “expiration date.” Business Insider
If Nvidia’s guidance slips, or cloud buyers pull back on storage orders, Sandisk—and other memory-linked stocks riding the AI boom—could take a hit.
Eyes turn to Sandisk’s comments at the Bernstein forum Wednesday, then Nvidia’s numbers hit after the bell. Thursday will tell if Citron’s Tuesday jolt leads to a real selloff, or if this is simply another bump in a stock that moves at the whim of the news cycle.
