SNDK Prints a Record as the NAND Trade Outlasts Western Digital's Exit

The Move Is the Memory Trade, Not the Window

The price that set Western Digital's exit was locked in over the June 16–18 VWAP window, so this latest leg to a fresh record isn't the reflexive bid into that measurement anymore — that mechanic is done. What's left is the trade that's powered the entire year: a structural NAND shortage with pricing power tilted hard toward the supplier. SanDisk has pushed flash prices up roughly 50% into AI-driven demand, and industry contract prices are running well into the double digits quarter-over-quarter with no near-term relief in sight. Apple reportedly flagged the memory-and-storage crunch as unsustainable, and that's exactly the tell memory bulls want: when the largest hardware buyer on earth says higher prices are unavoidable, the NAND names hold the leverage in every contract negotiation. Enterprise SSDs now make up close to a quarter of SanDisk's revenue, and that's the line the AI capex story flows straight through.

Western Digital Finally Walks Out the Door

Today is the mechanical close of Western Digital's exchange of its final 1,038,681 SNDK shares, a stake worth north of $2 billion, swapped with institutional investors for WDC stock. The number of WDC shares each counterparty hands over was fixed by the SanDisk VWAP over June 16–18, so the settlement happening today has no bearing on where the tape prints now. What it does do is clear the last block of former-parent stock out of the structure. Western Digital spun SanDisk off in 2025, and this is the final unwind of that relationship — the overhang of a known, motivated seller sitting on a multi-billion-dollar position is gone after today. For a stock that's run nearly 6,000% since the spinoff, removing that supply question is not nothing, even if it isn't what's driving the candle.

The Bear Case Is Just Math Now

None of this makes the valuation comfortable. SNDK trades around a 75x trailing multiple after a 700%-plus YTD run, and price has lapped a sell-side consensus that still sits near $1,600 — even with Bank of America, Mizuho, and Susquehanna all raising targets, the published range runs from roughly $250 to $3,250, which is a polite way of saying nobody knows how to model peak-cycle NAND earnings. The technicals are stretched too, with RSI pinned in overbought territory as the stock makes new highs. Today's 4.29% over 14 hours is also a noticeably calmer tape than the ~11.5% single-day prints earlier in the week, which reads either as digestion or as the first sign momentum buyers are getting filled. On a thin perp book those moves get amplified in both directions, and a name this far above consensus is exactly where profit-taking tends to show up first.
