SK Hynix dominates the high-end AI memory market (HBM3E/HBM4E) with a massive technological lead, trades at an attractive 8x forward P/E despite 60% QoQ profit growth, and has a NASDAQ listing catalyst expected in August that could unlock US institutional inflows. Key risks include cyclical semiconductor downturn exposure, potential contract cancellations from hyperscalers if AI monetization slows, and concentration risk from being 70% allocated to a single stock.
