How we classify it
Not counted as a concentrated manager: it is a private equity or venture firm; its stocks are usually holdings that went public. 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.
