Industry codes and annual filing references come from the SEC submissions snapshot linked to each issuer in our company catalog (snapshot ; newer filings may exist). Only groups with at least three distinct issuers, business descriptions and annual filing links are included. Multiple share classes of one issuer count as one company. This is a coverage directory, not a complete industry census or a ranking of investments.
