Samsung closed 4/28 at ₩222,000, down 1.1% from ₩224,500 — a healthy pullback after a vertical rally from ₩167k in late March. Q1 2026 preliminary operating profit hit ₩57.2T (+755% YoY) driven by HBM3E shipments to NVIDIA/Google/AMD and HBM4 mass production, with HBM revenue tripling YoY. Dip-buying on this pullback into the strong AI-memory narrative (SK Hynix record profits reinforcing the cycle) should push up on 4/29.
