Reported positions
not published in this buildThis build does not ship the holdings list, so the per-filer position list is not served here. Public Filings decided on 2026-08-01 to serve this list from its published build; a build that has not published it says so rather than showing an empty table. The primary source is the filing itself:
Book shape
Tick = median of the 8,035 tracked filers with a 2025-09-30 book (the index median: the 7,935 with a complete book). Concentration uses reported 13F long value, not total assets; the index is withheld when any position lacks a value.- 53.3%below median 79.6%
- integer Herfindahl–Hirschman index in basis points over disclosed position values
- 167 bpsbelow median 440 bps
- holdings with no disclosed value (undisclosed, or unreadable on the filing) — kept and counted, never shown as zero
- 109 / 109median book 102 positions

The filing on EDGAR is the record, including any filed after this build.
Open Burgundy Asset Management Ltd.'s 13F filings on SEC EDGAR ↗A 13F is a quarterly, long-only snapshot filed up to 45 days late — not current holdings. what a 13F covers ↗
13F reports cover LONG positions in Section 13(f) securities (US exchange-traded equities plus reportable options, warrants, certain convertibles) held by managers with at least $100M in such securities — so managers below that threshold are absent entirely. No short positions, no cash, no non-13(f) assets — not a full portfolio, and not a census of institutional ownership.
Positions are quarter-end snapshots filed up to 45 days late — not current holdings: a position may have changed or closed since the quarter ended.
Values are the manager's stated market value at quarter-end in era-dependent units (whole dollars for form versions effective 2023-01-03 onward, thousands before), normalized here to whole dollars; each record notes its original unit.
Affiliated managers may report the same position, so one position can appear under more than one filer.
Positions under confidential treatment may be omitted until a later amendment discloses them.
These are disclosures, not investment advice.
