What it reported after the quarter end (Q2 2026)
The 13F shows the portfolio as of Jun 30, 2026. Since then Winmill has filed these own trades with the SEC (Form 4, when it owns more than 10% of a company or holds a role in it) and stakes above 5% (13D and 13G). It is not everything it did: only what it must report before the next 13F.

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.
