How Copio researches and publishes
Clear authorship, traceable sources and explicit limits help you judge an article for yourself.
Who is responsible
Copio is published by Julius Müller. Articles identify their author, and personal bylines link to an author profile.
Sources, calculations and limitations
Articles cite their sources. When we publish calculations, we explain the data, observation period, currency, assumptions and material limitations. Downloadable data is provided where available. Historical results describe the studied period and do not guarantee future outcomes.
How AI is used
AI tools may assist research, calculations, drafting and translations. An AI-generated answer does not establish that a claim is correct. Published findings must be supported by sources, methods and disclosed limitations.
Updates and corrections
If a source changes or an error is identified, we correct the affected claim and update the article’s modification date when the content changes materially. Send corrections with the article URL and the supporting source.
The purpose of these articles
The articles provide financial information and education. They do not provide personalised investment advice.
