The position list above is served from the published Public Filings build, each position as this filer reported it; where the page cannot embed every reported row, the list says how many it leaves out. This block is provenance, not a substitute: the filing itself is the record, and it is one click away. Public Filings decided on 2026-08-01 to serve this list from its published build; filings newer than this build are on EDGAR.

Notes on this data

Quarter-end holdings as filed

Explore the full published position list and its source filing. This record excludes the manager’s cash, shorts and non-13(f) assets.

Compare consecutive quarters

Position changes retain the producer’s classification and comparability flags. Share counts and reported values describe different changes.

A snapshot, not current holdings

Use the quarter selector to inspect available periods. Unknown values stay unknown and each table states its coverage.

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 been changed or closed before you ever see it, and is older still by however long ago that 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 with unit_basis carried on every record.

Affiliated managers may report the same position (otherManager), 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 (ARCHITECTURE.md §5.2 / M2-CONTRACT §5).
