Ask the maps

26 value chains, 243 stages and every listed company placed where it earns its money — asked in plain English rather than clicked through. Questions about numbers are answered from the same figures the screener uses; questions about how an industry works are answered from the written analysis, with a link to the stage it came from.

What this is and is not. It answers from this site only — the placements, the figures and the written analysis — and says so when a question falls outside them. It describes how industries are structured; it does not recommend anything, and it is not investment advice. Figures in tables are rendered from the site's own data, not written by the model. Medians hide the spread inside a stage, and a good company in a weak stage routinely beats a weak one in a good stage.
