How the largest companies in Germany are ranked
Market value is price times shares outstanding, stored in US dollars so companies quoted in different currencies compare. Where market value and share count do not reconcile (several share classes, dual listings), the company is left out of the size ranking rather than shown with a wrong number.
There are no quality filters here: this is size, not merit. The fair value gap and the one-month probability are shown for context.
Limits: market values move every day with prices and exchange rates, and the figure shown is the latest ATLAS has stored. A large company is not automatically a safe or cheap one. This is information, not investment advice.
