Sandisk’s plunge looks like profit-taking inside an intact memory upcycle, and the market is treating a valuation reset like a thesis break. That read misses the most important fact on the board: the company just posted a blowout quarter with revenue up 97% sequentially and gross margin at 78.4%, which is not what a cracking NAND story looks like. The stock has earned a violent shakeout after a 534% YTD run, but the business backdrop still says pricing power and datacenter demand remain very real. We’d treat this selloff as a sentiment event first and a fundamental warning second.
The cleanest support for the bull case is still the operating performance. In fiscal Q3 2026, Sandisk delivered $5.95 billion in revenue, up 97% sequentially, alongside 78.4% gross margin and $4.11 billion in GAAP operating income. Those are not “good enough” numbers from a cyclical hardware name; they are peak-strength numbers from a company riding real supply discipline and strong customer demand. Management also framed the business around multi-year customer engagements with firm financial commitments, which matters because it suggests this cycle has more structure than the usual commodity memory boom-and-bust.
The demand story also looks broader than a one-quarter squeeze. Earlier in fiscal Q1 2026, Sandisk said datacenter revenue rose 26% sequentially, with two hyperscalers in qualification and engagement with five major hyperscale customers. That is exactly the kind of customer mix expansion bulls want to see in an AI memory winner: not just better pricing, but deeper strategic relevance. The market is also still getting confirmation from the tape around expectations. Sandisk has beaten earnings in 6 straight reported quarters, including a 59.7% EPS surprise in April and a 75.1% surprise in January, which tells us consensus has consistently been behind the curve.
The broader setup still supports the stock even after a huge run. Industry commentary continues to point to NAND undersupply through end-2026 and potentially into 2027, while recent analyst calls stayed firmly constructive. Consensus still sits at 13 buys and 2 holds with no sells, and recent target hikes from major firms came after the latest rally, not before it. That matters because today’s 14.1% drop happened against bullish research and still-strong news flow, which is exactly what a profit-taking flush looks like. Even the TickerSpark Score leans that way: an overall 77 with perfect 100 scores in Profitability, Financial Health, and Momentum says the internals remain far stronger than the panic in the share price suggests.
The bear case is easy to state: SNDK is expensive, crowded, and vulnerable to multiple compression. A 57.23x trailing P/E, 19.60x sales, and 47.01x EV/EBITDA are rich by any standard, especially against peers like KEYS at 36.20x earnings and FLEX at 1.80x sales. The stock is also coming off a breathtaking run, so a sharp air pocket was always possible once traders started harvesting gains.
There are also a few blemishes worth respecting. The headline growth table shows EPS down 142.4% year over year and net income growth down 144.2%, while insiders logged 5 recent sells and no buys. Those are not ideal optics. Still, the stronger read is that valuation risk explains the drop better than business deterioration does, because the freshest operating data, the earnings beat streak, and the supply backdrop all point in the opposite direction. When the fundamentals stay hot and the stock falls anyway, the first suspect is positioning.
That leaves SNDK looking like a stock we’d buy on weakness only if the core memory-cycle signals stay intact. The key things to watch from here are Q4 guidance, gross margin durability, and any sign that hyperscaler qualification progress is slowing. If Sandisk keeps showing datacenter traction and NAND pricing discipline, this selloff will look like another shakeout in an ongoing uptrend rather than the start of a deeper unwind.
We would still respect the volatility because this is a high-beta semiconductor name with an ATR above 210 and a stock that can move violently when momentum breaks. But with shares still above the 50-day moving average of 1,610.45 and far above the 200-day at 703.36, the bigger trend has not broken. The trigger that changes our mind is simple: evidence that pricing power is peaking. Until that shows up, the bull case still wins.
