- Source posture: public SEC Form 13F-HR filing-derived context. 13F data is delayed and limited to reportable securities and certain options/classes.
- SEC XML information table checked:
infotable.xml. The aggregate amount above is the sum of the filed XML value fields as reported; the draft intentionally avoids a thousands-of-dollars conversion because the filed XML values and share counts aligned at the reported-field scale in spot checks.
9AT filing context
SEC 13F data for the period ended 2026-03-31 shows 15,589 information-table entries and an aggregate reported value-field total of about 618.5 billion. This uses the filed XML value fields as reported, without multiplying by 1,000, because the spot-checked top entries reconcile to share counts at that scale; it remains a delayed public-securities snapshot, not total firm AUM, a complete portfolio, or a recommendation.
What to watch
Watch the next 13F filing for changes in top reported entries, option exposure, issuer concentration, amendments, or material shifts that may sharpen the due-diligence read. Where the manager has significant private-market or multi-strategy activity, also watch adviser filings and primary manager announcements because 13F alone is incomplete.
