About us
Opulion was born from a simple question: when you own a listed investment company, what do you really own? We answer it company by company, with dated and sourced figures.

Why Opulion
Listed investment companies let an individual invest alongside families and managers who think long term: the Wallenberg family behind Investor AB, the Agnelli family behind Exor, Belgian families behind Sofina or Ackermans & van Haaren.
But what they hold is hard to read: many holdings, listed or private, described in long reports that differ from one company to the next. Opulion lays them out with a single classification: one page per company, a journal for the news, and a portfolio to see what you hold across several companies.
Our commitments
- Independence: no mandate, no retrocession, no issuer to please.
- Every figure carries its date and its source. What is missing is declared missing.
- No investment advice: we inform and we analyse; the decision is yours.
- The author holds some of the companies we follow. He declares it on every company page, and the full policy is on the Independence page.
