SanDisk (SNDK) Falls -34% Over 30 Days as AI Memory Selloff Intensifies

Key Takeaways

• SanDisk (SNDK) shares fell roughly 34% over the last 30 days, from about $1,487 to approximately $978, as a broad AI and memory selloff hit the NAND flash sector.
• The steepest move came on November 5, 2026, when the stock dropped 22.26% in a single session to close at $806.43 amid post-election fears of tighter AI data center regulation.
• SanDisk's latest quarterly results beat consensus on revenue and earnings, but softer-than-expected Edge and consumer revenue and slowing NAND price gains spooked investors.
• The decline was driven primarily by macro and sentiment shifts rather than company-specific deterioration, including a midterm-driven AI de-rating and a memory-cost warning from Qualcomm.
• An approved 8-for-1 stock split, with split-adjusted trading expected to begin in late November, added a corporate-actions layer to the volatility.

SanDisk (SNDK) Company Overview and Market Position

SanDisk Corporation is a pure-play NAND flash memory and storage company headquartered in Milpitas, California. It was spun off from Western Digital (WDC) in February 2025, allowing investors to own the flash business independently. SanDisk develops and manufactures NAND-based storage solutions, including enterprise solid-state drives (SSDs) for AI data centers, embedded and edge products for smartphones, PCs, and automotive applications, and consumer memory cards and drives.

The company operates its flash manufacturing through the Flash Ventures joint venture with Japan's Kioxia, giving it large-scale fabrication capacity. A key part of SanDisk's strategy is its "New Business Model" — multiyear supply agreements with large data center and edge customers that carry floor pricing and financial guarantees. Investors follow SNDK closely because its fortunes are tied to NAND pricing, AI infrastructure spending, and the broader memory cycle.

SanDisk (SNDK) Stock Price Performance: Last 30 Days vs. Quarter

Over the last 30 days, SNDK has fallen approximately 34%, sliding from a closing price of about $1,487.33 on October 12, 2026, to $977.69 on November 11, 2026. The decline was not linear: shares held near the $1,400 level in mid-October before accelerating lower in late October and early November, including the 22.26% single-day drop on November 5.

The broader quarterly trend has also been negative. The stock peaked near $1,887 in late September before entering a sustained downturn, and it now sits roughly 58% below its all-time high near $2,354 set in June 2026. The pullback reflects a rotation out of high-multiple AI-linked memory names even as SanDisk's underlying fundamentals remained strong.

What Drove SNDK Stock Price in the Last 30 Days

The primary catalyst was a macro-driven de-rating of AI and memory stocks. On November 3, 2026, Democrats swept the U.S. midterm elections, and markets began pricing in the risk of tighter regulation and permitting constraints on AI data center construction, electricity use, and power consumption. Because SanDisk's enterprise NAND demand is closely tied to data center expansion, the sector-wide sentiment shift hit the stock hard.

The selling intensified after Qualcomm (QCOM) reported results on November 4 and flagged "industry-wide memory dynamics" in the smartphone market, raising concerns that elevated memory prices could pressure device demand. On November 5, the Nasdaq Composite fell more than 5%, and semiconductor indexes dropped sharply, with SanDisk closing down 22.26% at $806.43.

Company-specific news was comparatively strong. SanDisk reported fiscal first-quarter 2027 results on October 29 with revenue of $11.03 billion, up 378% year over year, and non-GAAP gross margin of 85.1%. Data center revenue rose 61% sequentially to $4.80 billion, while Edge revenue of roughly $5.8 billion and consumer revenue both came in below expectations. The stock still fell around 13% after earnings, as investors focused on decelerating sequential growth and moderating NAND price gains. A subsequent 8-for-1 stock split announcement and a November 11 product reveal (the iNAND CL EM181 embedded flash drive) helped shares partially recover.

What Drove SNDK Stock Performance Over the Last Quarter

Over the past three months, SNDK moved from strength into a sharp correction. After rallying through the summer on record NAND pricing and explosive AI-driven data center demand, the stock peaked near $1,887 in late September. From there, profit-taking, concerns that NAND prices could not sustain their elevated levels, and growing anxiety about an AI infrastructure slowdown gradually eroded the valuation.

SanDisk's fundamentals remained robust during the period — it generated strong free cash flow, expanded its long-term supply contracts, and maintained aggressive buybacks — but the market's focus shifted from earnings momentum to the sustainability of the cycle. The November election outcome accelerated the unwind, as regulatory and power-availability risks for data centers became a central concern. The result is a stock that has given back more than half of its value from its June peak despite reporting record results. From what I see, this highlights how sentiment can override strong fundamentals in the short term.

SNDK Stock Forecast Drivers: What Investors Should Watch Next

Looking ahead, several factors will shape SNDK's trajectory. NAND pricing remains the most important variable — any signs that memory prices are stabilizing or rolling over will directly affect revenue and margins. Investors should watch SanDisk's fiscal second-quarter results and, critically, guidance for the seasonally weaker fiscal third quarter, where management has historically flagged declining bit shipments.

Data center capital spending and the regulatory environment for AI infrastructure are equally significant, given that data centers now represent a large share of revenue. Developments from memory peers such as Micron Technology (MU) and Western Digital (WDC), as well as the execution of SanDisk's 8-for-1 stock split, will also influence sentiment. Competitive supply additions and any softening in hyperscaler spending remain key risks to monitor. I’m watching this closely as the next earnings cycle unfolds.
