Canonical: https://valuechain.wiki/hd-hyundai-heavy-industries · Facet: ripple · Updated: 2026-07-12T03:54:59.471+00:00 · Source: ValueChain.wiki (cited money-flow graph)

**Citable summary**: Per the valuechain.wiki graph, HD Hyundai Heavy Industries is directly linked to 3 companies (1 supply, 1 revenue, 1 investment relationships) and reaches 3 companies within two hops; the links are backed by 5 dated sources, 3 of them primary filings (as of 2026-07-12).

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.
