Institutional ownership from SEC Form 13F filings. Investment managers with more than $100 million in U.S. equities must disclose their positions every quarter, within 45 days of quarter-end, so the holdings shown can lag the market by up to a quarter.
Institutional holdings are being reconciled with SEC filings. Holder totals and changes may be incomplete until reconciliation finishes.

Each kind of 13F filer's share of the common shares 13F filers report. Holder type comes from regulatory
records, never the filer's name; style, turnover and horizon are measured from each filer's own 13F book.

The Sep 30, 2026 filing window is still open, so its
bar shows only the filers that have filed so far.
How the mix is measured
Shares are 13F common shares restated to today's split basis; options and principal amounts are left out.
The change compares only filers with a 13F in both quarters and keeps each filer in its bucket of the later
quarter on both sides; a filer that continues under a new CIK is compared through its successor. Holder type
comes from each filer's current regulatory profile; client base and private funds come from the Form ADV roster
current at each quarter end (rosters from December 2019, so an earlier quarter reads Unknown). Style, turnover, horizon and
book size are measured from each filer's 13F book in the newest measured quarter, and Not measured means none
was. Actively managed books are those measured systematic-like, concentrated or diversified active.
Excluded 1 holder with no observed 2026-03-31 13F.
Conviction and Crowding
44 13F filers, quarter ended Sep 30, 2024
Measured across every 13F filer's common-share book once the quarter's filing window closed. Crowding counts
filers with high turnover or that advise private funds on Form ADV.

Estimated Holder Cost Basis
Quarter ended Sep 30, 2024, on that quarter's share basis
Estimated, never filed: each 13F buy is costed at its quarter's average traded price and each sale keeps
the average cost, so this is what holders paid on average if they traded evenly through each quarter.

New and Sold Out count only filers that reported a 13F for both quarters: a first-time filer's book is not a buy, and a fund that has not filed, or withheld its positions under confidential treatment, has not sold.
