Morgan Stanley’s latest memory note doesn’t argue the trade is over — it argues the easy part is. $MU $SNDK $WDC $STX have run on a combination of pricing surprise, inventory drawdown, and relentless upward earnings revisions. The firm now says all three of those engines are running out of runway at the same time, even as it keeps the structural bull case for 2027 fully intact.

The Thesis

The setup Morgan Stanley describes is “peak rate of change,” not “peak cycle.” DRAM price growth is still positive but decelerating year-over-year, the inventory improvement curve has flattened rather than continuing to steepen, and earnings estimate revision breadth for DRAM has reportedly reached roughly 89% — a level that leaves almost no room for further upgrades to surprise the market. None of that requires demand to actually weaken. It just means the stocks have been pricing in acceleration, and acceleration is the one thing that’s statistically hard to repeat once revision breadth is already near-universal. The next real catalyst, in MS’s framing, is Q2 2026 hyperscaler earnings and capex commentary — a beat-and-raise on cloud capex extends the story, a cautious tone on AI spend, token monetization, or “chipflation” passthrough gives the correction thesis its opening.
