Every boom has a supply chain, and the market prices the famous names first. Pick an industry, follow the chain outward, and surface the suppliers-to-the-suppliers that most investors never look at β then run a DD report on anything interesting. π marks under-the-radar names.
About this map: relationships are curated and simplified β a company can sit in several chains, and segment membership means "meaningful exposure", not exclusivity. Under-the-radar tags highlight less-covered names, which are often smaller and more volatile. Nothing here is a recommendation β it's a starting point for your own DD.
