How to read these figures?
Rates come from the 5 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.
