Sandisk Round-Trips an Intraday Pop as the AI-Memory Trade Keeps Unwinding

A Round-Trip on No News

$SNDK is down 5.43% over two hours to about $1,658, erasing an early double-digit pop and rolling back into the red. There's no company-specific headline behind it — no earnings, no guidance cut, no downgrade. What's unwinding is one of the most extreme momentum runs in the market: Sandisk is up roughly 570% in 2026 and nearly 4,000% over the past year, and it tagged an all-time high of $1,831.50 on June 3 before this week's chop. With a beta north of 3, a 5% two-hour swing here is just the daily weather, not a signal.

The Whole Memory Complex Is De-Risking

The pressure isn't isolated to Sandisk. The entire NAND and DRAM complex has been unwinding together, with Micron and Western Digital selling off alongside it. Two things lit the fuse last week: a cautious AI-chip outlook from Broadcom and fresh competition worries in memory, and rumors that NVIDIA's next Rubin platform could need less memory capacity — a direct shot at the AI-NAND demand story. The semiconductor sector shed roughly $1 trillion in market cap in the rout. Layer on a jittery tape ahead of SpaceX's $1.77 trillion IPO on June 12, which the market is treating as a referendum on growth-tech valuations, and the highest-beta names get sold first.

Positioning, Not the Thesis

Here's the divergence worth sitting with. Even as spot fades, the sell-side is moving the other way: BofA lifted its target to $2,100 from $1,550 and Mizuho went to $2,200, both well above the current price. The fundamentals haven't cracked either — last quarter Sandisk posted revenue of $5.95 billion, up 251% year over year, with non-GAAP EPS of $23.41 against a $14.66 consensus, and locked in $42 billion of multiyear supply backlog. None of that changes in a two-hour candle. This is leveraged positioning getting flushed out of a parabolic name, not the AI-memory thesis breaking — which is exactly why the moves are this violent in both directions.
