What is CGEM institutional ownership?
This page tracks CGEM positions reported by institutional investment managers through SEC Form 13F. CULLINAN THERAPEUTICS INC (CGEM) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own CGEM?
InsiderSet currently tracks 177 institutional managers reporting CGEM 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 CGEM shareholders.
How much CGEM stock do institutions own?
Institutional investment managers disclosed approximately $1.30B in CGEM holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was CGEM institutional ownership last updated?
The latest CGEM 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 CGEM 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 CGEM position after the reporting date.
Are institutions buying or selling CGEM?
Institutional buying and selling can be analyzed by comparing CGEM positions across consecutive 13F reporting periods. InsiderSet's CGEM Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View CGEM ownership changes.
