Memory giant SanDisk SNDK has emerged as the undisputed standout performer in the S&P 500 during the first half of 2026, with its shares skyrocketing an incredible 858%. This meteoric rise, fueled by explosive demand for its NAND flash memory, has made it the top-gaining stock in the index, leaving the second-best performer, Micron Technology MU, which gained around 300%, far behind.
For investors who missed this remarkable surge, the key question is how to gain exposure without investing in a stock at an elevated valuation.
One prudent alternative is to consider exchange-traded funds (ETFs) that hold SanDisk as a top component. This approach offers diversified exposure to the company’s potential while mitigating the risks associated with its current lofty valuation and the inherent volatility of individual memory stocks.
But before diving straight into those ETFs, one needs to understand the growth catalysts that drove SNDK to such high levels and whether they are sustainable over the long run; otherwise, gaining exposure to SanDisk-heavy ETFs will be meaningless. This understanding is crucial for a prudent investor to make an informed decision.
What Drove SanDisk to Skyrocket in H126?
The primary catalyst behind SanDisk’s historic surge was the rapidly accelerating artificial intelligence (AI) infrastructure buildout across the globe. Since AI models require massive, high-speed storage for training and inference, demand for enterprise solid-state drives (SSDs) skyrocketed over the past few quarters. This demand boom led to a powerful pricing cycle and significantly higher average selling prices for data storage devices like those manufactured by SanDisk.
Furthermore, SanDisk’s spin-off from Western Digital allowed it to operate as a pure-play NAND company, making it a direct beneficiary of this AI-driven storage boom without the distraction of a legacy hard-drive business.
The numbers speak for themselves: SanDisk’s fiscal third-quarter 2026 datacenter revenues rose 233% sequentially to $1.47 billion, with Enterprise SSDs now representing about 25% of the company’s overall portfolio. This remarkable growth underscores just how deeply AI-led demand boom for NAND technology is bolstering SanDisk’s business trajectory.
SNDK’s Growth Potential & the Case for ETFs
Despite SanDisk’s massive rally in recent months, the stock still has further upside potential. As the memory chip shortage is expected to persist, with industry projections suggesting supply-demand imbalances could continue through 2027, explosive demand for NAND flash will continue to outstrip supply. This should continue to fuel SNDK’s rally, at least in the near term.
