The One-Line Thesis
SK Hynix is the largest identified valuation anomaly in the semiconductor sector, sitting at a 60%+ PE discount to Micron with a US listing catalyst 2-3 months out.
Trading at 5.85x forward PE into DRAM pricing +176% YoY (Goldman), 4.9% undersupply — the worst in 15+ years — and a June/July ADR listing confirmed to underwriters (Korea Herald, Apr 16). The ADR triggers SOX/SMH/SOXX index inclusion, unlocks US institutional mandates, and historically closes 30-80% of the discount to domestic peers (see TSMC precedent). Q1 earnings April 29 is the next datapoint. M15X fab opens May. This is not a product cycle — it's a platform transition where memory has become the binding constraint on AI.
