by shares · Δ value · filing link · how changes are classified §Positionposition matched across quarters by exact reported CUSIP over a registry gap — producer-reconciled identity, never a name match identity_reconciled_by_cusip | Changethe reported share count is unchanged across the pair, so the position reads as held rather than as a buy or a sell; only builds before this release inferred a direction from the reported value instead classified_by_value · "exit" = absent this quarter: disposed, delisted, under confidential treatment, or reported instead by an affiliated manager — the filing does not say which · change not classifiable: value undisclosed on one side of the quarter pair, or neither shares nor value can classify it · "no change" = the share count is identical in both quarters; the value moved only with price, so the row is mark-to-market and never an add or a trim (Add / New / Trim / Exit / No change) · "no prior" = this filer has no comparable holdings list for the previous quarter on record — a first filing under this registration, or a quarter reported inside an affiliated manager's filing — so the position is not called a new stake | Δ valuederived by Public Filings from the published aggregate; NULL means the source did not disclose a usable value — never zero | Δ shares | Prev value | Curr value | Prev shares | Curr shares | Flags |

Positions whose share count is identical in both quarters; the value changed with price, not with a decision.
Positionposition matched across quarters by exact reported CUSIP over a registry gap — producer-reconciled identity, never a name match identity_reconciled_by_cusip | Changethe reported share count is unchanged across the pair, so the position reads as held rather than as a buy or a sell; only builds before this release inferred a direction from the reported value instead classified_by_value · "exit" = absent this quarter: disposed, delisted, under confidential treatment, or reported instead by an affiliated manager — the filing does not say which · change not classifiable: value undisclosed on one side of the quarter pair, or neither shares nor value can classify it · "no change" = the share count is identical in both quarters; the value moved only with price, so the row is mark-to-market and never an add or a trim (Add / New / Trim / Exit / No change) · "no prior" = this filer has no comparable holdings list for the previous quarter on record — a first filing under this registration, or a quarter reported inside an affiliated manager's filing — so the position is not called a new stake | Δ valuederived by Public Filings from the published aggregate; NULL means the source did not disclose a usable value — never zero | Δ shares | Prev value | Curr value | Prev shares | Curr shares | Flags |

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).
