How we classify it
Type not verified. It meets the portfolio criteria of a concentrated manager, but its type is not verified: we found no official document that is enough to say what kind of entity it is. It may be an investment firm, but also an adviser adding up client accounts, a bank or a family vehicle. It counts in the tallies like the rest; keep that in mind when reading it. How the type is assigned
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.
