SanDisk Slides to $1,574 as Samsung's Sell-the-News Rolls Into a Third Session

The Catalyst

The selloff traces straight back to Samsung Electronics. The company posted a preliminary Q2 operating profit of 89.4 trillion won — roughly $58 billion, a record haul driven by AI memory demand, with revenue up 129% year over year to 171 trillion won. On paper that's a blowout. But Deutsche Bank flagged that the print landed only about 6% above estimates, and after Samsung shares had already run ~150% into the number, the reaction was a textbook sell-the-news. Memory peers went with it: Micron and Western Digital both sank around 7% alongside SanDisk as capital rotated out of the group. There is no SanDisk-specific headline in any of this — it's a sector sentiment reset.

The NAND Glut Overhang

Underneath the sell-the-news sits a more durable worry. Samsung and SK Hynix are both adding NAND and DRAM capacity at the exact moment research desks warn that hyperscaler AI capex may peak in 2026. More supply into cooling demand growth is precisely what erodes average selling prices — and ASPs are the whole story for a pure-play. Where a diversified chipmaker can lean on other lines, SanDisk's output is priced largely off the NAND spot market, so it wears the glut fear more directly than almost any name in the group. That's why it dropped 11% in a single session last week while Micron slid only 4%. This latest leg is the same trade, still unwinding.

What's Actually Priced In

The move is a valuation problem dressed up as a catalyst. SanDisk is still up roughly 635% in 2026 and trades north of 70x trailing earnings, which leaves almost no margin for error when sentiment turns. The Street is openly split on it: Bank of America lifted its target to $2,500 and Bernstein went to $3,000, while Morningstar flags 20-30% downside from stretched valuation. The next real test is the August 13 earnings report, where consensus looks for EPS near $33 against $0.29 a year ago. Until then this is a positioning trade, not a fundamentals one — and the $1,574 print is already a bounce off the $1,511 low, so the tape is reversing fast in both directions.
