Memory Supercycle — DRAM/NAND/HBM Structural Tightness
Memory Supercycle — DRAM/NAND/HBM Structural Tightness
Memory is in a structural tightness cycle, not a normal trough-to-trough one. Independent of any strike: TrendForce Q2 2026 contract prices DRAM +58-63% / NAND +70-75% QoQ (after ~95% Q1 jumps); an IDC-sized supply deficit DRAM 4.9% / NAND 4.2% / HBM 5.1%, worst since ~2011; HBM ~23% of DRAM wafers; new fab capacity not in volume before late 2027/2028. The Samsung NSEU 18-day strike (from 2026-05-21, ~45k workers, talks collapsed 2026-05-12) is a verified transient catalyst layered on top — bullish for competitor pricing near term, but a bonus-formula dispute that could settle fast; logged in log.md as a dated event, NOT as the thesis. Cohort strong-up but uniformly 7d red as of 2026-05-18 — no Samsung-strike rotation pop into MU; the complex sold off with the KOSPI. Late on the trade, mid-cycle on the thesis. Born 2026-05-19 from the verified memory supply-shock research note.
Watch for: Samsung NSEU strike actually starting 2026-05-21 + post-2026-06-07 mediation (fast settlement kills the strike angle, not the thesis), memory-vs-foundry line split during the strike (April test: memory -18% / foundry -58%), MU outperformance vs Samsung 005930.KS during the strike window (the competitor-pricing mechanism test — absent so far), spot DRAM/NAND price reaction after 2026-05-21, whether the cohort's 7-day pullback resolves up or breaks trend, MU / SK Hynix quarterly prints (citation of record for the contract-price thesis)
