How to read these figures?

Rates come from the 40 official filings published by SIX Exchange Regulation. A filing is only required when a threshold is crossed (3, 5, 10, 15, 20, 25, 33⅓, 50, 66⅔%): the actual position may have changed since.

Estimated value = shares held per the latest filing × latest CHF closing price. It is an indicative order of magnitude: the position may have changed without a new threshold being crossed, and holdings without a share count or a CHF price are not valued. Each company's mini-chart traces the successive declared rates.

This profile shows only what the declarant published. No external data is added to it.

Group structure

Shareholding disclosures are often filed jointly by several entities of the same group. The registry links them together: "Controls" lists the group entities declared alongside this shareholder, "Controlled by" the head entities. The figure is the number of joint disclosures, followed by the date of the most recent one.
