SanDisk Draws a $294 Million Bet While Wall Street Trims Its Enthusiasm

South Korea's National Pension Service built a fresh $294 million stake in SanDisk during the third quarter of 2026, according to media reports published today covering the fund's holdings disclosure. The position, worth that amount at the end of September, ranked as the largest single new purchase in the filing. NPS held no SanDisk shares at the close of June.

The timing is striking. The fund moved in while worries about a slowdown in AI spending were weighing on valuations across the sector — and just as at least one brokerage was turning more cautious on the stock.

Fox Advisors downgraded SanDisk from "Overweight" to "Equal-Weight" on November 2, a call that landed alongside a broader retreat in technology shares reported by the Associated Press. The AP account points to concerns about investment levels and valuations in the AI industry as the force dragging US equities lower. SanDisk had already slipped a day earlier, giving back ground after a sharp advance in the prior session.

What the Pension Fund Is Really Buying

For anyone trying to read the NPS entry, the more useful question is what sits behind the business rather than the share-price chart. Multi-year supply agreements could give SanDisk more dependable visibility on sales — provided the terms hold up.

Management says such contracts cover roughly half of production volume in fiscal 2027 and two-thirds in fiscal 2028. Negotiated floor prices are meant to protect a gross margin of about 80%. That structure argues for better planning certainty as long as the minimum prices stay effective, which makes execution on those deals — converting paper into profitable shipments — the number to watch. After a strong run in the price, the contractual backstop carries extra weight.

Demand from data centers offers a second leg of support, so long as buildout continues and customers honor their offtake commitments. The research house behind the downgrade still sees multi-year supply contracts and AI data centers underpinning the outlook.

A Split, Not a Sell-Off

Separately, SanDisk is preparing for split-adjusted trading to begin on November 20 following its announced eight-for-one stock split. Shareholders of record on November 9 are set to receive seven additional shares for each one they hold. The start date has been announced as an expectation.

To be clear, the split is a mechanical adjustment: it multiplies the share count and divides the price, leaving the value of each investor's holding unchanged. It is not a verdict on the company's prospects.

Other Filings in the Mix

Jane Street Group disclosed economic ownership of 3.7% of SanDisk's share class as of September 30, reporting the stake on November 6 through an amended Schedule 13G/A filing.

Weighing it all together, the case for the NPS position rests on concrete operating conditions: whether the data-center business keeps expanding and whether the agreed floor prices keep profitability intact. Those are the terms on which the durability of this new institutional bet will ultimately be judged.
