How we classify it

Not counted as a concentrated manager: more than 20% is ETFs; it is an insurer whose portfolio we have not reviewed by hand. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided

Managers of a similar size

A 13F portfolio value between a third and three times this one, whatever the type of filer. It is not a comparison of what they hold.
