Open Elm Partners Management LLC'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.
