Every other ranking on this site compares a company with the rest of its index. That is useful, but it means a software company is measured against banks and a bank against miners — and the metrics do not travel. Price-to-book flatters anything that owns heavy assets and punishes anything that does not, which is why the methodology page tells you to compare within sectors in your head.
This page does it for you. Every company we track is ranked inside its own sector, across all 30 indices at once. The lens you choose still decides what counts; the universe is what changes.
