SanDisk Stock Crashes 19% as SNDK Loses 36% in Six Sessions

SanDisk (NASDAQ: SNDK) suffered another sharp decline on Thursday, November 5, with its shares falling around 19% as investors continued to pull back from memory-chip and Artificial Intelligence infrastructure stocks. The latest drop extended a six-session losing streak that erased approximately 36% of the company’s market value over the period.

The sell-off has been striking because it came shortly after SanDisk reported strong quarterly earnings and issued an upbeat outlook. The company’s results suggested that demand for NAND flash storage remained robust, particularly from data-centre customers. Yet investors appeared more concerned about the sustainability of that demand, the possibility of new competition from China and the risk that the next phase of AI infrastructure investment could be slower than expected.

SanDisk was not alone. Micron, Western Digital, Seagate and other semiconductor-related stocks also declined, pointing to a broader reassessment of the memory and AI hardware trade rather than a single company-specific problem. Political uncertainty following the US midterm elections and concerns about data-centre expansion added another layer of pressure.

The central issue is that strong current earnings do not automatically guarantee that investors will continue paying high valuations for future growth. SanDisk’s recent performance shows how quickly sentiment can change when expectations for an entire industry come under pressure.

Why did SanDisk stock fall nearly 19% on November 5?

SanDisk’s November 5 decline reflected several concerns converging at the same time. The most important was a broad retreat from memory and semiconductor stocks as investors reconsidered the outlook for AI-related infrastructure spending.

Data centres require substantial amounts of storage and memory to support artificial intelligence systems, cloud computing and large-scale data processing. SanDisk supplies NAND flash storage products used in these markets. That exposure has helped support its recent growth, but it also makes the company sensitive to changes in expectations for data-centre investment.

Investors have begun questioning whether the enormous spending plans associated with AI infrastructure will continue at the pace previously anticipated. Concerns about electricity costs, regulatory scrutiny, construction delays and the ability of technology companies to generate returns from AI investments have added uncertainty.

That uncertainty has affected companies supplying the infrastructure, including memory-chip manufacturers. When investors become less confident about future demand, they may reduce exposure to the companies most closely linked to that spending, even if their latest financial results remain strong.

SanDisk’s decline was also amplified by weakness across the wider semiconductor market. Micron and other memory-related companies recorded significant losses, while Qualcomm faced separate concerns about its smartphone-chip business. The simultaneous declines suggested that investors were reducing risk across several parts of the technology sector.

China’s CXMT expansion adds pressure to the memory-chip industry

Another concern for memory investors is the growing presence of Chinese semiconductor manufacturer ChangXin Memory Technologies, commonly known as CXMT. The company has been expanding its memory-chip business, raising questions about future competition in an industry dominated by a relatively small number of major global suppliers.

China has made semiconductor self-sufficiency a strategic priority. Its domestic chipmakers have received significant attention as the country seeks to reduce reliance on overseas technology suppliers and develop more of its own semiconductor manufacturing capacity.

For established memory producers, the potential expansion of Chinese competitors creates uncertainty about future market share, pricing and supply. If additional manufacturing capacity enters the market, buyers could eventually have more suppliers to choose from. That could influence pricing power, particularly if production expands faster than demand.

However, the competitive implications should not be overstated. SanDisk’s business is heavily associated with NAND flash storage, while CXMT is primarily known for DRAM memory production. These are related but distinct memory markets, with different products and applications. CXMT’s expansion does not automatically mean that it is directly replacing SanDisk’s NAND products.

The wider concern is that China’s growing semiconductor capabilities could reshape competition across the memory industry over time. Investors may be considering how new capacity, government support and domestic demand could affect the balance between supply and demand in different memory segments.

For SanDisk, the issue is therefore partly about industry sentiment. Even when a competitor does not directly target the same product category, the prospect of greater memory-chip competition can make investors more cautious about the sector’s long-term pricing outlook.

AI data-centre spending concerns threaten the growth narrative

SanDisk has benefited from the rapid expansion of artificial intelligence infrastructure. AI systems require large quantities of data to be stored, retrieved and processed, creating demand for high-capacity storage solutions in data centres.

NAND flash memory plays an important role in this infrastructure. It is used in solid-state drives and other storage products that help data centres manage large volumes of information. As companies develop AI models and expand cloud computing capacity, demand for enterprise storage can increase.

This connection has helped investors view memory suppliers as beneficiaries of the AI investment cycle. But the same connection can become a risk when expectations about data-centre spending change.

Investors are increasingly examining whether technology companies can convert their large AI investments into sustainable revenue and profits. If returns take longer to materialise, companies could become more selective about capital expenditure. That could slow the pace of new data-centre construction and affect suppliers across the hardware chain.

Political developments have added to these concerns. Following the November 3 US midterm elections, investors began assessing whether changes in congressional control could lead to greater scrutiny of AI infrastructure projects, electricity demand and data-centre expansion.

Such concerns do not establish that data-centre investment will stop or that new restrictions will necessarily be introduced. They do, however, create uncertainty about the speed and cost of future projects. For a company whose growth expectations are closely linked to AI-related storage demand, uncertainty about that investment cycle can have a significant effect on its share price.

Qualcomm’s handset revenue decline adds to semiconductor sector pressure

Qualcomm’s latest results provided another negative signal for semiconductor investors on November 5. The company’s shares fell sharply after its smartphone-chip sales missed Wall Street expectations, raising concerns about weakness in its core handset business.

Qualcomm reported that revenue from its handset division fell 26% to $5.14 billion. Revenue from its chip segment declined 8% to $9.02 billion. The figures highlighted the pressure facing a major part of its business even as the company works to expand into data-centre and automotive chips.

Qualcomm’s results are not a direct measure of SanDisk’s business. The companies operate in different parts of the semiconductor supply chain, and weaker smartphone-chip revenue does not automatically translate into lower NAND flash demand.

However, the results contributed to a more cautious mood across the technology sector. Investors were already questioning the strength and durability of AI-related spending, while Qualcomm’s performance highlighted the challenges facing established chip businesses outside the strongest growth areas.

Higher memory costs have also become a concern for smartphone manufacturers. Rising component prices can pressure device makers and affect demand, creating another connection between the memory market and the broader consumer electronics industry.

The combination of weaker handset trends and uncertainty over AI infrastructure made it harder for semiconductor stocks to find support during Thursday’s trading session.

SanDisk shares fall despite record earnings and a stronger forecast

The contrast between SanDisk’s financial performance and its share-price movement is one of the most important parts of the current sell-off. The company reported its fiscal first-quarter 2027 results on October 29, delivering substantial revenue growth and a significant increase in profitability.

SanDisk reported revenue of approximately $11.03 billion, up 23% from the previous quarter and 378% from the same period a year earlier. GAAP net income reached $8.1 billion, while non-GAAP diluted earnings per share came in at $49.51.

The data-centre business was particularly strong. Revenue from this segment reached $4.80 billion, compared with $2.98 billion in the previous quarter. That represented sequential growth of 61%. The company’s edge business also increased, while consumer revenue declined.

SanDisk’s outlook was similarly positive. For fiscal second-quarter 2027, management forecast revenue between $12.2 billion and $12.6 billion. The company also projected non-GAAP diluted earnings per share of $55 to $57, based on the pre-split share count.

These figures indicate that SanDisk entered the latest sell-off with strong reported demand and an optimistic near-term financial outlook. The weakness in its shares therefore appears to reflect changing expectations about future industry conditions, rather than a disappointing quarterly report.

Investors are effectively weighing two different questions: how much revenue SanDisk can generate under current market conditions, and whether the growth rate can remain strong as competitors expand capacity and customers reassess their AI infrastructure budgets.

SanDisk stock forecast: Why analyst price targets remain divided

Analyst opinions on SanDisk have remained divided despite the company’s strong earnings. Some analysts continue to see significant potential in its exposure to data-centre storage, while others have become more cautious about the stock’s valuation and near-term risks.

Price-target estimates available after the earnings announcement showed a wide range. Some analysts maintained bullish targets, including a $3,000 target from Bernstein. Other firms had reduced their expectations or maintained more conservative positions.

Fox Advisors downgraded SanDisk from Overweight to Equal Weight on November 2. The move added to concerns about the stock’s near-term trajectory after its substantial gains. Wells Fargo also reduced its price target, while several other firms adjusted their targets following the company’s results.

The range of estimates illustrates the uncertainty surrounding the stock. Analysts who remain optimistic may be placing greater weight on SanDisk’s strong data-centre growth, its earnings outlook and the long-term demand for enterprise storage. More cautious views may reflect concerns about valuation, competition, memory pricing and the possibility of slower AI infrastructure spending.

Investors should also distinguish between a published price target and a guaranteed future share price. Analyst targets are estimates based on assumptions about earnings, demand, competition and market conditions. Those assumptions can change quickly, particularly in a cyclical industry such as memory chips.

SanDisk’s sharp decline does not automatically invalidate the bullish forecasts, just as strong earnings do not guarantee that the stock will recover immediately. The gap between optimistic and cautious estimates reflects how differently market participants are interpreting the same industry outlook.

Why SanDisk-linked ETFs can move in opposite directions

SanDisk’s volatility can also affect exchange-traded funds that hold its shares or provide exposure to semiconductor stocks. However, different ETFs can respond very differently to the same movement in SNDK.

A conventional technology or semiconductor ETF may hold SanDisk alongside companies such as Nvidia, Micron, Qualcomm and other chipmakers. In that case, the effect of a SanDisk decline depends on the stock’s weighting within the fund and the performance of its other holdings.

Leveraged and inverse ETFs follow different strategies. A leveraged fund seeks to multiply the daily performance of an underlying index or basket of securities, while an inverse fund seeks to move in the opposite direction. As a result, two products connected to the same semiconductor market can record sharply different daily returns.

There is another important distinction: an ETF that holds SanDisk directly is not the same as a fund that tracks a semiconductor index or a leveraged technology strategy. Their performance depends on their underlying holdings, exposure and investment structure.

Investors should therefore examine an ETF’s holdings and stated objective rather than assuming that every fund linked to memory chips will move in line with SNDK. During a volatile period, daily leveraged returns can also differ substantially from the simple multiple of a stock’s performance over several trading sessions.

SanDisk announces an 8-for-1 stock split

SanDisk announced an eight-for-one forward stock split on October 29, the same day it released its quarterly earnings. The company said the decision was intended to make its shares more accessible, including to employees participating in its stock purchase plan.

Under the announced arrangement, shareholders of record at the close of trading on November 9, 2026, will receive seven additional shares for every share they own. The additional shares are scheduled to be issued after the market closes on November 19, with split-adjusted trading expected to begin on November 20.

An eight-for-one split changes the number of shares held by investors and reduces the price per share proportionately. For example, an investor holding one share before the split will hold eight shares afterward. The theoretical per-share price will be one-eighth of the pre-split price, assuming no other market movement.

The stock split does not create additional company value by itself. It does not increase SanDisk’s revenue, profits or market capitalisation. Instead, it changes the number of outstanding shares and the price represented by each share.

The announcement should also not be confused with a direct explanation for the November sell-off. A forward split is a corporate action affecting the share structure, whereas the recent decline has been associated with wider market concerns, industry competition and uncertainty about AI-related spending.

What the six-session decline means for SanDisk investors

The speed of SanDisk’s decline highlights the risks associated with stocks whose valuations depend heavily on expectations of future growth. Even companies reporting strong financial results can experience significant price corrections when investors begin questioning whether those results can be sustained.

For SanDisk, several factors now require attention. The first is whether data-centre demand continues to grow at the pace reflected in its latest results. The second is whether the company can maintain strong margins as memory supply and competition evolve. The third is whether AI infrastructure investment remains strong enough to support the industry’s growth expectations.

The company’s latest earnings provide evidence of strong current business performance. Its data-centre revenue growth and second-quarter guidance are important indicators that demand remains substantial. But the Stock Market is forward-looking, and investors are also assessing what conditions could look like several quarters from now.

The wider memory industry is cyclical. Supply shortages can support higher prices and margins, but additional manufacturing capacity can eventually change the balance. If supply grows faster than demand, pricing pressure may emerge. If demand remains strong while supply is constrained, memory producers could continue benefiting from favourable market conditions.

China’s expanding semiconductor capabilities add another variable to that outlook. Although CXMT’s current product focus is not identical to SanDisk’s NAND business, its growth contributes to wider questions about competition and future memory supply.

What to watch next: Earnings, AI investment and memory demand

Several developments will help investors assess whether SanDisk’s decline is a temporary market correction or part of a longer reassessment of the company’s growth prospects.

• Data-centre revenue: SanDisk’s ability to maintain growth in its enterprise and data-centre storage business will remain a key measure of demand.
• Second-quarter performance: Investors will compare upcoming results with the company’s revenue forecast of $12.2 billion to $12.6 billion.
• Memory pricing: Changes in NAND supply, pricing and production capacity could influence future revenue and margins.
• AI infrastructure spending: Investment decisions by cloud providers and technology companies will help determine the longer-term demand outlook for storage products.
• Chinese competition: Developments involving CXMT and other domestic semiconductor manufacturers could influence investor expectations about the wider memory market.
• Analyst revisions: Further changes to earnings estimates and price targets may indicate whether Wall Street is becoming more cautious or regaining confidence.

The November 20 stock-split date is another event shareholders should understand, although it does not change the underlying value of their investment. Investors should evaluate the company’s financial performance and business outlook separately from the mechanical adjustment in its share price.

Is SanDisk stock facing a temporary correction or a deeper slowdown?

SanDisk’s latest sell-off reflects a difficult combination of strong company results and weakening market confidence in the broader AI and memory-stock trade. Its quarterly earnings showed substantial growth, particularly in data-centre revenue, and management issued a positive forecast for the following quarter.

At the same time, investors are reassessing the assumptions that helped drive memory stocks higher. Concerns about data-centre spending, regulatory uncertainty, competition from China and weakness across the semiconductor sector have increased pressure on the shares.

The distinction between business performance and stock-market expectations is important. SanDisk can continue reporting strong revenue while its shares remain volatile if investors believe future growth has already been reflected in the valuation or if risks to the industry’s outlook increase.

For now, the company’s next results, data-centre demand trends, memory-market conditions and broader AI investment plans will be important indicators to monitor. The recent decline alone does not establish whether SNDK has reached a bottom or whether further losses are ahead.

The key question is no longer simply whether SanDisk is benefiting from AI demand. Its latest results show that it is. Investors are now trying to determine how durable that demand will be, how much competition the company may face and whether its future growth can justify the valuation the market previously placed on the stock.
