MU & SNDK Update: Where We Are Tuesday Night, and What's Actually Next

Micron prints fiscal Q3 after Wednesday's close, SanDisk is sitting on a 200-point air pocket, and the Korean memory cascade is the only macro signal that matters into the print. Here's where MU and SNDK are right now, what the tape is telling me, and the three scenarios I'm trading.

Editorial illustration of a glowing HBM memory stack with MU and SNDK ticker lines diverging into red and green, a pre-market clock reading 4:05 PM overhead, signaling Micron's after-the-close earnings catalyst.
Plate 31 — One catalyst left between this dip and a real reassessment of the AI-memory trade: Micron, Wednesday, 4:05 PM ET.

Quick update on MU and SNDK now that the dust has settled on Tuesday's session.

Micron closed near the lows of the gap, SanDisk gave back roughly 200 points and stayed there, and the rest of the U.S. memory complex (WDC, STX) traded with them. The Korean session that started this — KOSPI down 10%, Samsung and SK Hynix liquidated, halt tripped — did not reverse into the close. That is the relevant overnight signal heading into Micron's print.

Below: where the two names actually closed, what the options tape is pricing, the three scenarios for Wednesday after the bell, and how I'm sized.
