SanDisk Slides to $1,650 as Supply-Glut Fears Crack the NAND Bull Case

The Catalyst: A Supply Scare, Not a Broken Story

For a couple of weeks the memory-stock selloff read as pure rotation and profit-taking after a historic run. This leg has a sharper edge. Reporting on the move pins it on memory supply-glut fears: announced supply additions from Samsung and SK Hynix are expected to soften memory pricing as supply catches up with demand, while AI capital expenditure is seen peaking in 2026 and tapering thereafter. That reframes the entire trade — the thing that turned NAND from a boom-bust commodity into a cash machine was tight supply and firm pricing, and that is exactly what is now in question.

The macro backdrop did the rest. Fed Chair Kevin Warsh flagged that asset valuations were becoming stretched, and Morningstar's research director warned AI names could fall 20% to 30% before becoming buyable. The Philadelphia Semiconductor Index dropped more than 6% on July 1, and the epicenter was Asia, where SK Hynix fell more than 14%, Samsung roughly 9%, and SanDisk's own NAND partner Kioxia dropped as much as 12% in Tokyo.

Why SanDisk Falls Hardest

SNDK is the highest-beta expression of the memory trade, so it takes the largest hits when the group sells off. After a roughly 640% year-to-date gain and more than 6,000% since the February 2025 Western Digital spin-off, the stock trades north of 60x earnings against a 52-week high of $2,354.39 — a valuation that leaves no cushion for a pricing scare.

The deeper issue is exposure. SanDisk's revenue is unusually leveraged to spot pricing: only about one-third of anticipated fiscal 2027 revenue is locked under contract, and roughly 60% of NAND output is subject to spot-market pricing. If supply additions soften NAND prices, that flows straight through to earnings rather than being buffered by long-dated contracts. That mechanism is why a 6% index drop became a 10% to 14% SNDK session, and why it has kept bleeding to $1,650 over the days since.

The Bull Case Analysts Won't Abandon

The sell side is not blinking. Bank of America and Citigroup both target $2,500, Bernstein sits at $3,000, and China Renaissance raised its target to $3,169 in an 86% hike. UBS argues DRAM stays undersupplied until at least the second quarter of 2028 and framed the pullback as likely temporary; on July 6, SNDK, Western Digital and Micron bounced 3% to 5% as those desks reiterated their bull calls.

The fundamentals underneath are still loud: Micron just posted fiscal Q3 revenue of $41.46 billion, up 346% year-over-year, and guided Q4 to $50 billion, while SanDisk and Kioxia began production of tenth-generation 3D NAND at the Kitakami Fab2 plant in Japan. The bull read is that this is a positioning washout inside a structural upcycle, not a broken thesis. The risk is timing: there is no SanDisk earnings print until August, so sentiment — not fundamentals — runs the tape until then.
