Every boom has a supply chain, and the famous names usually get priced first. Pick an industry, follow the chain out to the smaller suppliers, and run a DD report on anything that looks interesting. π marks less-covered names.
About this map: relationships are curated and simplified. A company can sit in several chains, and being in a segment means meaningful exposure, not exclusivity. π tags mark less-covered names, which are often smaller and more volatile. Nothing here is a recommendation; it's a starting point for your own DD.
