What is AGEN institutional ownership?
This page tracks AGEN positions reported by institutional investment managers through SEC Form 13F. AGENUS INC (AGEN) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own AGEN?
InsiderSet currently tracks 105 institutional managers reporting AGEN 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 AGEN shareholders.
How much AGEN stock do institutions own?
Institutional investment managers disclosed approximately $44.06M in AGEN holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was AGEN institutional ownership last updated?
The latest AGEN 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 AGEN 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 AGEN position after the reporting date.
Are institutions buying or selling AGEN?
Institutional buying and selling can be analyzed by comparing AGEN positions across consecutive 13F reporting periods. InsiderSet's AGEN Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View AGEN ownership changes.
How has AGEN institutional ownership changed over time?
InsiderSet tracks AGEN institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
