SanDisk Slides to $1,424 as CXMT's $9.8 Billion IPO Deepens Memory Oversupply Fear

What Cracked the Buy Wall

SNDK is down 13.8% to about $1,424, roughly 39% below the June 22 peak of $2,354. The proximate trigger was Argus initiating coverage with a Hold — the first non-buy on the tape after a near-unanimous bull consensus. The firm likes SanDisk's position in NAND flash but warned that "any tempering in demand could cause a severe reaction in product pricing and the share price", the exact cyclicality risk a parabolic run tends to ignore.

The number that makes a single Hold this dangerous is the multiple: SNDK still trades near 60 times trailing earnings, and Argus is now the lone Hold against roughly 18 active buy ratings. Nothing in the business broke here — profits are still modeled to more than triple next year — so this reads as sentiment repricing pace, not a fundamental crack.

China's $9.8 Billion Memory Bet

The reason a Hold could do this much damage is what is happening on the supply side of the whole memory complex. In the same week, China's CXMT priced a Shanghai STAR Market IPO at 8.66 yuan a share, targeting up to about $9.8 billion — the largest mainland listing since 2010, with proceeds earmarked to upgrade production lines. CXMT is the world's fourth-largest DRAM maker at roughly 8% share, and it is explicitly building to challenge Samsung, SK Hynix, and Micron.

CXMT is DRAM-first and SanDisk is NAND, so the hit is thematic rather than head-to-head: China pouring state-backed capital into memory just as the group has gone vertical hardens the oversupply fear that has hung over every memory name. It landed alongside TSMC beating on earnings but lifting its capex guide toward $60 billion, a second signal that the industry is adding capacity into the boom. Blockonomi tied the Argus Hold and the CXMT filing directly to SanDisk's leg lower — the supply story finally has receipts.

The Setup Into August 5

The tension is that the sell-side is still overwhelmingly long. Evercore sits at $3,100 and Bernstein at $3,000, with BofA and Citi at $2,500, and Goldman recently lifted its target to $2,200 on a constructive NAND supply-demand view. Even through the drop, several desks kept raising numbers rather than cutting.

Positioning is stretched on both sides: over 11% of the float is short and the stock trades more than 20% under its 20-day average, so the tape is a fight between a de-rating multiple and a still-bullish research desk. That argument gets settled on August 5, when SanDisk reports fiscal fourth-quarter results with the Street still modeling roughly $8 billion in revenue. Until the print, this is a repricing of pace and sentiment on a 2026 winner — not proof the business has turned.
