How we classify it
Not counted as a concentrated manager: its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%; 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.
