Why SanDisk (SNDK) Stock Is Up +21.5% in the Last 30 Days
Key Takeaways
- SanDisk shares climbed roughly 21.5% over the past 30 days, rising from $1,344.29 to $1,633.35.
- The move was fueled by a blockbuster fiscal fourth quarter, sharply higher NAND pricing, and a new multiyear data-center contract model.
- Over the last quarter, however, the stock remains down about 13% after a sharp mid-summer correction from record highs.
- SanDisk secured eight multiyear agreements worth roughly $93.9 billion in minimum revenue, improving earnings visibility.
- Upcoming S&P 100 inclusion and continued AI-driven storage demand are key watchpoints for investors.
SanDisk (SNDK) Company Overview and Market Position
SanDisk Corporation is a leading designer and manufacturer of NAND flash memory and data-storage solutions, including solid-state drives (SSDs), embedded storage, removable memory cards, and USB drives. The company returned to the public markets as an independent entity in early 2025 after separating from Western Digital, and it operates a long-standing flash-memory manufacturing joint venture with Kioxia.
SanDisk has repositioned itself from a cyclical memory supplier into a provider of high-value storage for artificial-intelligence data centers. Rising demand for NAND flash used in AI training and inference workloads has made the company a focal point for investors tracking the memory upcycle, alongside peers such as Micron Technology (MU) and SK hynix (SKHY).
SanDisk (SNDK) Stock Price Performance: Last 30 Days vs. Quarter
Over the trailing 30 days, SanDisk shares advanced approximately 21.5%, moving from a closing price of $1,344.29 to $1,633.35. The rally accelerated in early September, including a single-session gain of nearly 12% following news of the company's upcoming inclusion in the S&P 100 index.
The last quarter tells a more volatile story. After peaking near an all-time high around $2,354 earlier in the year, the stock corrected sharply through July and remains down about 13% from its mid-June levels near $1,881, even after the recent rebound. This combination of a strong 30-day bounce against a still-negative quarterly performance underscores how quickly sentiment around memory pricing can shift.
What Drove SNDK Stock Price in the Last 30 Days
The primary catalyst was SanDisk's fiscal fourth-quarter earnings report. Revenue surged 51% sequentially and 372% year over year to $8.97 billion, while gross margin expanded to 84.6%. Non-GAAP earnings per share of $39.25 beat consensus estimates of roughly $33.28. Full-year revenue reached $20.25 billion, up 175%, with data-center revenue climbing 437% year over year.
Management also guided to another record quarter, projecting revenue of $10.30 billion to $10.80 billion and gross margin of 83% to 84.9%. The company authorized a $14 billion share repurchase program, adding further support to the stock.
SanDisk's investor day reinforced the bullish narrative. The company outlined a fiscal 2028–2030 model targeting roughly 80% gross margins, about 75% operating margins, and approximately 50% adjusted free-cash-flow margins. It also disclosed eight "New Business Model" agreements with data-center customers representing about $93.9 billion in minimum revenue, covering roughly half of fiscal 2027 bit shipments and two-thirds of fiscal 2028 volume.
Broader industry dynamics added momentum. Analysts noted tight NAND supply, with UBS projecting memory average selling prices to rise more than 20% in the third quarter and expecting the undersupply to persist into 2027. SanDisk and Kioxia also announced plans for a roughly $31 billion investment in Japan to expand flash-memory capacity.
What Drove SNDK Stock Performance Over the Last Quarter
The quarterly decline reflects a classic memory-cycle dynamic. After an extraordinary run that lifted shares more than 500% year to date, investors grew concerned that NAND pricing gains—which drove roughly two-thirds of the company's recent sequential revenue growth—could not be sustained indefinitely. Those worries triggered a correction of more than 50% from the record high into the late-July lows.
The subsequent rebound was driven by a fundamental shift in how the market values the business. Management's long-term contracts and profitability targets are designed to reduce the boom-and-bust volatility that has historically defined the NAND industry. This reframing, combined with strong earnings and continued AI-infrastructure spending, helped investors re-enter the stock even as broader technology sentiment remained mixed.

SNDK Stock Forecast Drivers: What Investors Should Watch Next
Several factors will shape SanDisk's trajectory in the months ahead. The fiscal first-quarter 2027 earnings report will be critical for validating management's revenue and margin guidance, as well as confirming that NAND pricing remains firm. Investors should also monitor the ramp of the company's multiyear customer agreements and the commercialization of high-bandwidth flash technology.
On the macro front, semiconductor tariff uncertainty, memory-supply expansion from competitors, and any slowdown in hyperscaler capital spending are key risks. Given the stock's elevated volatility and substantial year-to-date gains, valuation and technical positioning will remain important considerations as the market weighs durable AI-storage demand against the historically cyclical nature of NAND pricing.
