Stakes above 5% (13D/13G)
Companies where this filer reported holding 5% or more of the shares. It is the figure from its latest filing on each one; history since December 2024.
How we classify it
Not counted as a concentrated manager: it has fewer than 8 quarters of history; its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%; it is a bank or trading desk; its positions are usually hedges or inventory. 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.
