How it is calculated
A sector's weight. For each concentrated manager we add up the weight of its positions in that sector within its 13F portfolio, then average across all of them. Every manager counts the same, whatever its size: it is not the share of total money. Stocks we could not classify weigh 2.7%; with them, the weights add up to 100%.
Where each company's sector comes from. From the industry code (SIC) the company reports to the SEC, mapped to eleven sectors with a published table, plus a short list of manual corrections. See the table.
How managers are counted. For each stock, how many concentrated managers held it at the end of the previous quarter and how many at the end of this one. A company that went public in the quarter goes from 0 to many: that is why both figures are shown, not just the difference. Who the concentrated managers are.
It is a snapshot of a quarter that has already closed: portfolios as of June 30, 2026, public by August 14, 2026. A 13F does not include short positions, bonds, cash or stocks not listed in the United States. Research information; not investment advice.
