SanDisk Breaks $1,600 as the NAND Oversupply Case Gets Specific

Why the Selloff Kept Going

SNDK is down 12.88% over the last 24 hours to about $1,547, and this is a continuation, not a fresh shock. The proximate trigger was Argus Research initiating coverage on July 15 with a Hold — the lone Hold on the name — warning that "any tempering in demand could cause a severe reaction in product pricing and the share price". The stock fell about 7.3% intraday on the note and kept bleeding into the next session, slicing through $1,600 and retesting the $1,500 shelf. After a run that took the stock up roughly 800% in the first half of the year, it doesn't take much to unwind a crowded trade — one credible skeptic was enough to start it.

The Bear Case Is About Price, Not Demand

The distinction that matters here: nobody is calling for a demand collapse. The fear is that NAND average selling prices normalize faster than the bull case assumed. Argus modeled a cyclical downturn that could drag profits back toward 2026 levels by 2030 as supply catches up — the exact opposite of the perpetually-rising-price narrative that justified a ~60x trailing multiple. This isn't SanDisk-specific either. Earlier this month, Morningstar's Lorraine Tan warned that AI names could give back 20% to 30%, singling out memory as the most exposed because announced supply additions from Samsung and SK Hynix are expected to soften pricing while AI capex peaks in 2026. That call took the whole complex down together — SanDisk off 11%, Seagate 7%, Micron 4%, Western Digital 7% in a single session — which is why this reads as a sector repricing, not an idiosyncratic stumble.

The Supply Story Is Now Trading Publicly

Part of what's spooking the tape is that competing NAND capacity is about to be listed and priced right next to SNDK. Kioxia — SanDisk's own manufacturing joint-venture partner — is preparing a US debut that some frame as a cheaper way to own the same supercycle. The two firms co-develop process technology and split fab costs at Yokkaichi and Kitakami, and their JV just started BiCS10 production at the Kitakami K2 line in early July. New capacity coming online — from SanDisk's own partner — at the exact moment the market is fretting about a 2027 supply wave is the picture bears keep pointing to. A giving investor a listed, cheaper alternative also caps how much scarcity premium SNDK can hold onto.

The Setup Into August 5

The analyst spread on this name is unusually wide, which is why it moves the way it does. Against Argus's lone Hold sit a wall of bulls: Goldman Sachs at $2,200 with a Buy, Bank of America at $2,500, and per recent notes Evercore at $3,100, Bernstein at $3,000, and Citi at $2,500. With beta near 3.8 and a valuation that only works if NAND pricing stays firm, the stock trades every incremental data point as a referendum. The resolution point is close: fiscal Q4 earnings land on August 5, the first hard read on whether selling prices are holding or already rolling. Until that print, this is a sentiment tape, and sentiment just turned.
