SEC Form 13F-HR quarterly institutional holdings — the legally mandated public report (public domain, 17 U.S.C. §105) every institutional manager with >=US$100M discretion must file within 45 days of quarter-end. Panel shows a bounded curated subset of star managers (CIKs verified against EDGAR submissions JSON; registry re-verified on each admission, latest 2026-08-28; candidates not verifiable as actively filing — e.g. Scion, Greenlight, Omega Advisors, Pabrai — were honestly dropped), latest quarter top-10 holdings plus quarter-over-quarter frame diff (new/increased/reduced/exited on share counts, with a whole-USD value delta = current − prior quarter as-filed value; full position value on new/exited, and on increased/reduced the value sign may oppose the share move — price drift). Values are as filed in the EDGAR 2014+ information-table XML (whole USD — the 'expressed in thousands' note is the legacy HTML rendering); same-(CUSIP, class, option) tranches merged into one position; shares as filed (SH lines; option lines flagged PUT/CALL). Filing-date point-in-time; amendments supersede (latest filing per report quarter wins). Issuer→ticker links are exact normalized-name matches (case/punctuation/apostrophes/legal suffixes) against the terminal's US stock universe and the SEC company_tickers snapshot (current, not as-of-filing; ambiguous multi-entity names dropped) — EDGAR infotables carry CUSIPs, not tickers, and as-filed abbreviations stay unmatched plain text. The value/growth/activist/macro/quant/china_background/other category tags are HUMAN-CURATED editorial metadata written in the fetch registry — they do NOT exist in any SEC data source. Display-only, not a research claim; NOT part of any OOS pipeline.
