How we classify it
Type not verified: we have not assigned a type because we found no document that is enough to tell. Most 13F filers are in this situation: we only review in depth those that meet the portfolio criteria.
Not counted as a concentrated manager: its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%. 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.
