Not shown: the top-five share — this build's concentration slices hold the top 25 positions, not five.
§ 'Reported 13(f) long value' is the sum of a filer's disclosed long positions for its latest quarter, which the value's note names — not assets under management: it excludes cash, shorts and non-13(f) assets, so a large multi-asset manager can appear small. n/a means the filing disclosed no usable value — never zero. A position reported without a value is left out of the sum and counted beside it; the concentration index (HHI) is withheld from display and from ordering whenever any value is missing.

1–10 of the 50 newest changes by notable managers shown here These rows are notable managers' new, added, trimmed and exited positions, at most two per manager, newest filing first, then largest change; each manager's full list is on its filer page.

They can be derived from the filings on EDGAR.Quarter-over-quarter comparisons are between two quarter-end snapshots of what was reported — not a record of transactions, and not a claim about what any manager holds now.
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).

The window is a quarter, never a rolling day count — quarterly filings cannot support one — and only quarters whose 45-day filing deadline has passed are offered, because an open quarter counts only the managers who filed early.

| the rank number is produced by the active sort, not held by the row — ordering by it would be circular, so it renumbers with every sort instead | "issuer" is an issuer key, not a ticker: its source may be a resolved entity link, a CUSIP-6 issuer block, or a normalized reported name, and each is a weaker claim than the one before it. The key and its source are printed so the strength of the identity is visible | a partial sum omits at least one position whose value the source did not disclose. It is a lower bound on what was added, never a total — and an issuer whose every contributing delta was undisclosed renders an em dash, never $0 | the top adder is the manager whose positions in this issuer sum to the largest disclosed increase this quarter — summed across every security of the issuer first, then ranked, so a manager holding several share classes is not split into pieces that each look small | ||
