Micron Smashes Records: The Semiconductor Signal That Could Halt the Tech Sell-Off

A record quarter for Micron reshuffles the deck after ten days of tech correction - but the real test remains the same-day PCE reading.

The Fact

Micron Technology reported a record quarter in fiscal Q3 2026, driving Nasdaq futures higher in pre-market trading on June 25, 2026. The DRAM/NAND memory manufacturer is benefiting from structural AI demand: HBM (High Bandwidth Memory) modules for AI servers now account for a growing and majority share of server memory revenue. The Nasdaq-100 had lost 3% on June 23 in a widespread Big Tech sell-off fueled by the Fed Warsh's hawkish repricing.

Our Take

Micron serves as a leading indicator of AI infrastructure spending: a record quarter signals that hyperscalers' CAPEX remains strong despite the market correction. The momentum is counter-cyclical to the sell-off—major tech stocks may be correcting, but they continue to invest heavily in compute and memory. For the Nasdaq, the technical rebound post-Micron is testing the 19,200–19,500 pts resistance zone—a consolidation area identified as the base scenario. The June 25 core PCE reading will determine whether this rebound holds or if a second bearish wave resumes.

To Watch

• Micron’s Q4 guidance: any downward revision in HBM orders would trigger a renewed semis sell-off.
• June 25 core PCE: a binary pivot for the session—Nasdaq resistance or relapse.
• Impact on European semiconductors (ASML, STMicro) in the Paris session.
