Many questions are already answered in How the ranking works and on the about page: which companies qualify, how share classes are combined, where the figures come from, and how often the snapshot refreshes.

MarketCapLens does not provide investment, tax, or legal advice. Nothing sent here is a recommendation or a client relationship. See the disclaimer.

What to contact us about

• Possible errors in a listed figure or company page (include the ticker and what looks wrong).
• Questions about coverage — for example why a name is missing or combined with another class.
• Accessibility barriers, described on the accessibility statement.
• Privacy questions, covered in the privacy policy.
• Press or data-citation inquiries.
