About Us

K-Chain Radar tracks the Korean stock market through its value chains — the networks of companies that supply, build, and service each other across sectors like shipbuilding, defense, power infrastructure, secondary batteries, and biotech.

Instead of looking at one stock in isolation, we follow how capital and momentum move from node to node within a chain: from upstream material suppliers to assemblers to downstream service and maintenance providers. The goal is to catch sector rotation earlier by watching where the signal is already showing up one step ahead.

This blog is the English-language home for that research — longer write-ups expanding on the daily company notes we publish on X (@KChainRadar), aimed at readers outside Korea who want visibility into the KRX market.

What we publish

  • Short profiles of individual companies and where they sit in their value chain
  • Notes on how a sector's chain is rotating, based on public disclosure and price data
  • Occasional context pieces on how a chain is structured

What this isn't

K-Chain Radar is a data and research publication, not a licensed investment advisor. Nothing here is a recommendation to buy or sell any security. See our Terms and Conditions for details.

What the company actually does The business traces back to 2016, when Hyundai Heavy Industries spun off its after-sales division into a separate company, Hyundai Global Service. From there it expanded into bunkering and digital-control businesses, and listed on the KOSPI in May 2024. Four segments make up the core business: Ship parts supply Bunkering (marine fuel supply) Eco-friendly retrofit work on existing vessels Digital solutions for fleet operation None of this depends on new ships being ordered.
