The largest institutional holders of SEB reported in the latest SEC Form 13F filings include Dimensional Fund Advisors Lp, Blackrock, Inc., Aqr Capital Management Llc, Vanguard Portfolio Management Llc, and Vanguard Capital Management Llc. InsiderSet ranks institutional holders by their latest reported SEB position.
What is SEB institutional ownership?
This page tracks SEB positions reported by institutional investment managers through SEC Form 13F. SEABOARD CORP (SEB) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own SEB?
InsiderSet currently tracks 208 institutional managers reporting SEB holdings in the latest available 13F data. This count reflects institutions included in the SEC Form 13F filings analyzed by InsiderSet and should not be interpreted as the total number of SEB shareholders.
How much SEB stock do institutions own?
Institutional investment managers disclosed approximately $1.09B in SEB holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was SEB institutional ownership last updated?
The latest SEB institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026. Form 13F filings are generally reported after the quarter ends, so the holdings shown represent the latest publicly disclosed positions rather than real-time institutional holdings.
Are institutional SEB holdings real-time?
No. Form 13F data is not real-time. It represents positions reported by institutional investment managers as of the end of the reporting quarter. An institution may have changed its SEB position after the reporting date.
Are institutions buying or selling SEB?
Institutional buying and selling can be analyzed by comparing SEB positions across consecutive 13F reporting periods. InsiderSet's SEB Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View SEB ownership changes.
How has SEB institutional ownership changed over time?
InsiderSet tracks SEB institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
