HD Hyundai Heavy Industries operates across KOSPI, Shipbuilding & engines, HiMSEN. After +86.9% in 2025, it corrected -22.6% in 2026. The supply side (avg -1.4%) has moved harder than the stock (-22.6%). That is the classic bottleneck pattern: supplier volume leverage is being priced before this layer's own margin. Among connected nodes the furthest ahead is POSCO Holdings (-1.4%) and the furthest behind is Hanwha Ocean (-37.3%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. HD Korea Shipbuilding is its parent; it exports warships and submarines to the Peruvian and Indian navies.
