SanDisk Retraces the Samsung Rout as the NAND Shortage Trade Holds

The Move Is a Retrace, Not a Catalyst

$SNDK is trading around $1,702, up 12.17% over the last 18 hours from roughly $1,517 — a continuation of the snapback that began once last week's memory selloff burned itself out. There is no fresh company-specific headline behind the July 7-8 tape. This is the market rebuying a name it dumped too hard: SanDisk fell about 23% across three sessions into the rout before turning, and the bounce has now clawed back most of that drawdown. On the HIP-3 side, the SNDK perp turned over roughly $323M in the last 24 hours, so there is real two-way flow behind the retrace rather than a thin-book squeeze.

The Rout Was Positioning, Not a Demand Warning

The drop everyone is now buying back started in Seoul. On July 7, Samsung posted preliminary Q2 operating profit of 89.4 trillion won — about $58.4 billion, up roughly 1,800% year over year on AI chip demand. That is a blowout, and the tape treated it as a top: Samsung itself fell 6.9%, with Micron and Western Digital down about 6% in sympathy. After SanDisk's roughly 3,750% twelve-month run, the stock was the most crowded profit-taking target in the group, so a positive print became an excuse to ring the register. Nothing in Samsung's numbers questioned NAND demand — if anything they confirmed it — which is why the selloff never held.

The Thesis That Didn't Move

The dip was buyable because the structural story is intact. SanDisk began sampling its BiCS10 1Tb TLC 3D NAND on July 3, a roughly 59% bit-density step that plants it squarely in the AI-storage buildout, and contract NAND pricing is still grinding higher through 2026. Micron's guidance points to tight memory supply persisting beyond 2027, and SanDisk's most recent quarter showed datacenter revenue up around 645% year over year. The sell side is still parked above spot — Bernstein at $3,000 and Bank of America and Citi at $2,500, with the broad analyst average near $2,035. The counterweight is valuation and beta: the stock is still up about 635% YTD, multiples are stretched, and Chinese supply from YMTC is a live risk. With next earnings due around August 13 and consensus EPS near $33.38 versus $0.29 a year ago, this stays a high-velocity name that mean-reverts hard in both directions.
