Sandisk, Micron and SK Hynix Slide 3% as NVIDIA Shake-Up Hits Memory Stocks

Sandisk (NASDAQ: SNDK) fell 3% to $950.98 in morning trading on November 12, dragged down by a leadership shock at NVIDIA that is spreading through the AI hardware supply chain. Micron Technology and SK Hynix fell in near lockstep, each down about 3% on the same day. The sell-off hit memory names specifically, even as the broader market gained ground.

The trigger sits at the top of the AI chip industry's biggest company. Jensen Huang resigned as chief executive of NVIDIA (NASDAQ: NVDA), and traders spent November 12 shaking off the CEO exit while the wider market turned positive. The NASDAQ 100 rose 0.3%, and technology ranked among the market's leading sectors. The divergence matters: memory makers slipped while the sector around them gained, which points the blame at sentiment toward AI hardware rather than a general tech selloff.

Why does a CEO exit hit memory stocks?

Memory makers sit close to NVIDIA in the AI supply chain. Its accelerators depend on high-bandwidth memory (HBM) — the stacked DRAM chips that feed data to AI processors at extreme speeds — and on fast data center storage. That structural link explains why Sandisk slipped while technology stocks broadly gained.

Profit taking in memory names may also be adding pressure, according to the report. Both drivers can operate at once, and neither is measurable from a single morning of trading.

Sandisk's decline comes one day after a Wall Street defense of the stock. On November 11, Evercore ISI reiterated support for Sandisk, pointing to stable NAND storage demand (NAND being the flash memory used in SSDs) and maintaining a $2,500 price target on the shares. That call gives the bulls a reference point. One analyst note still carries limited weight against a shock at the AI industry's biggest name.

Takeaway: the memory slide reflects supply-chain exposure to NVIDIA, not weakness in the memory market itself — at least on the evidence available.

How far did the damage spread?

The selling was concentrated in memory and storage names, and the pattern was remarkably uniform:

• Sandisk (NASDAQ: SNDK) — $950.98, down 3% in morning trading.
• Micron Technology (NASDAQ: MU) — $789.90, down 3%.
• SK Hynix (NASDAQ: SKHY) — $137.99, down 3%.

SK Hynix's American Depositary Shares (shares of a foreign company traded on a U.S. exchange) give U.S. buyers direct access to a major HBM producer. The Korean chipmaker reports in Korean won, which adds a currency layer for American holders of those shares.

Micron's exposure to the AI buildout runs wider than Sandisk's. Beyond NAND, Micron sells dynamic random-access memory (DRAM) and HBM, giving the company more products tied to AI accelerators than a storage-only supplier has. Yet the market punished both stocks identically on the day — a sign that traders priced the news by sector, not by product mix.

What sets Sandisk's pure NAND model apart?

Sandisk is a pure-play NAND flash supplier, spun off from Western Digital (NASDAQ: WDC) as an independent public company. Its business breaks down into three markets:

• Enterprise SSDs for AI infrastructure — its fastest-growing market.
• Edge devices — its largest end market.
• Retail storage — rounding out the lineup.

Sandisk sources its flash wafers from Flash Ventures, its manufacturing joint venture with Kioxia.

Micron runs a broader, vertically integrated model spanning DRAM, NAND, NOR flash and HBM, built on advanced process technology. Its Multi-year Strategic Customer Agreements are designed to make demand more durable. Sandisk takes a different contracting approach: long-term contracts with customer prepayments and deposits.

SK Hynix's core strength is high-bandwidth memory. It is the leading supplier of HBM for AI accelerators, including NVIDIA's — the very dependency that transmitted NVIDIA's leadership news into its share price.

Takeaway: the three companies sell different mixes of memory, but all three are levered to the same AI infrastructure spending cycle.

Is Micron's 4x forward P/E a bargain or a warning?

Micron trades at a trailing price-to-earnings (P/E) ratio of 10x and a forward P/E of 4x — its expected earnings over the coming year priced at four times their forecast level. Those are low multiples for a company at the center of an AI memory boom, and they may appeal to value-focused shareholders.

A very low forward P/E can carry a warning, too. Memory is a cyclical business, and a depressed multiple may signal that the market doubts Micron's peak earnings will last. The company's next earnings report could put that skepticism to the test.

Takeaway: the valuation says investors are paying for a downturn, not pricing a boom — and only results will settle which reading is right.

What comes next for the memory trade?

Sandisk's next test is whether AI data center demand for enterprise SSDs holds firm while NVIDIA works through its leadership change. The bulls can point to the stable NAND demand that Evercore ISI highlighted on November 11, and to Sandisk's fast-growing data center business, anchored by that $2,500 price target.

The bears see a stock that could stay volatile if AI spending plans face fresh scrutiny. SK Hynix and Micron face the same question, since all three companies lean on heavy AI infrastructure spending — the same capital cycle that made them AI-era winners in the first place.

Investors may want to be cautious while NVIDIA's leadership transition resolves, the report notes. Caution is warranted on the other side as well: a single morning of sector-wide selling says little about demand, and none of the three companies has reported any change in orders. The story here is sentiment, not fundamentals — until the next earnings print proves otherwise.
