composite

Memory Supercycle

members 5 weighting custom benchmark SPY

Weighted composite from the memory-supercycle lane (validated 2026-06-29): HBM cannibalizes DRAM, suppliers capture Mag7 capex. Overweights the DRAM/NAND primaries (MU, SNDK), carries Korea exposure via EWY, and keeps a tail in the HDD pair (STX, WDC).

Cumulative return since Sep 21 — both lines start at 0%, so the gap between them IS the out/under-performance. Hover for daily values.
