Sandisk surges 16.60%, hitting a record high; storage chip sector has risen over 40% since the end of April

SanDisk Performance

According to the Gold Shape APP, SanDisk (SNDK.US) closed up 16.60% on Friday, hitting another record high, with a single-day trading volume reaching $30.215 billion. This impressive performance solidifies its leading position in the storage chip sector and further fuels market enthusiasm for investment in the entire semiconductor memory field.

SanDisk, as a globally renowned storage chip manufacturer, has seen its share price surge over 40% since the end of April, making it, together with Micron Technology, one of the top performers in the Philadelphia Semiconductor Index and fully demonstrates the explosive potential of the memory segment.

Storage Prices

Spot prices of storage chips continue to rise, becoming a core catalyst for the stock price increase. Since the outbreak of the Iran war at the end of February, DRAM chip spot prices have risen by about 25%, and NAND flash memory chips have climbed about 18%. The rapid recovery in prices has directly improved profit forecasts for storage manufacturers, leading to a revaluation of relevant listed companies.

Drivers of the Surge

Analysts believe that this round of storage chip price hikes is caused by multiple supply-demand imbalances. The enormous demand for high-bandwidth memory in AI servers continues to absorb capacity, significantly squeezing memory supply for traditional consumer sectors such as PCs and smartphones. Meanwhile, capital expenditures in the industry have significantly contracted over the past two years, resulting in a slow release of new capacity that cannot quickly match the explosion of demand.

In addition, Middle East geopolitical conflicts have disrupted maritime logistics and driven up insurance costs, further tightening the supply chain. Korean companies account for over 60% of global storage chip supply, making regional instability factors more sensitive to global price transmission.

Micron Comparison

SanDisk and Micron Technology have shown highly coordinated performance in this market rally, with both companies achieving more than a 40% cumulative increase since the end of April. Micron rose 15.49% on Friday and broke through a market value of $800 billion, while SanDisk's single-day surge was even higher, demonstrating the market’s rotation and strong preference for leading memory stocks.

Both companies have deeply benefited from the price increases in DRAM and NAND, but SanDisk’s traditional strength in NAND flash gives it extra attention in data center and enterprise storage demand.

Risks and Opportunities

The storage chip sector is currently facing significant opportunities: high capital expenditure in AI will continue to support memory demand, and upward price momentum is expected to persist. However, risks also exist—if tensions in the Middle East ease and logistics recover, or if major manufacturers accelerate capacity expansion, prices could face short-term correction pressure. Investors should closely monitor geopolitical developments and changes in industry capital expenditure.

Editor’s Summary

Storage chip prices have rebounded significantly due to the dual effects of explosive AI demand and supply constraints, pushing leading companies such as SanDisk to all-time highs. Sector rotation is evident, with capital focusing more on the memory segment, but the sustainability of the rally depends on how the supply-demand balance and macro environment evolve.

Event Core Background: In May 2026, the storage chip market was jointly driven by surging high-bandwidth memory demand for AI servers and logistics tightening caused by Middle East conflicts. DRAM and NAND spot prices soared. The share prices of companies such as SanDisk and Micron Technology rebounded strongly as a result, with cumulative gains exceeding 40%, reflecting structural opportunities in the semiconductor cycle reversal.

FAQ

Q: What is the direct cause of SanDisk’s 16.60% single-day surge?

A: The continuous rise in storage chip spot prices has fueled optimistic profit expectations for the company. Coupled with the overall market hype around AI, capital has concentrated in leading memory stocks, resulting in a trading volume of $30.215 billion and pushing the stock price to new record highs.

Q: What is the practical impact of the rise in DRAM and NAND prices on storage companies?

A: The rise in prices directly boosts product gross profit margins and improves company profitability. With DRAM up about 25% and NAND up about 18%, companies like SanDisk gain strong performance support, while also attracting re-rating in the secondary market.

Q: Why has the storage chip sector performed exceptionally well this round?

A: The explosive growth in high-bandwidth memory demand for AI servers has squeezed out capacity from the consumer electronics sector. At the same time, the past two years of capital expenditure reductions caused slow supply response, and Middle East geopolitical factors further increased logistics costs. The supply-demand gap has jointly pushed up both prices and stock prices.

Q: What are the similarities and differences in the investment logic for SanDisk and Micron Technology?

A: Both benefit from rising storage prices, but SanDisk’s strength in NAND is more prominent, while Micron has a more comprehensive layout in both DRAM and overall technology. Currently, both have achieved cumulative gains of over 40%, showing sector linkage effects and providing investors with opportunities to diversify and capture the storage cycle.

Q: What risks should investors pay attention to when participating in the storage chip rally?

A: Watch out for easing geopolitical tensions that could restore supply, accelerated production expansions that may lower prices, and a slowdown in AI capex growth. It’s recommended to use professional tools to analyze technical trends, manage positions carefully, monitor quarterly results for validation, and avoid chasing highs that may result in volatility losses.
