What is CEG institutional ownership?
This page tracks CEG positions reported by institutional investment managers through SEC Form 13F. CONSTELLATION ENERGY (CEG) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own CEG?
InsiderSet currently tracks 1,870 institutional managers reporting CEG 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 CEG shareholders.
How much CEG stock do institutions own?
Institutional investment managers disclosed approximately $73.80B in CEG holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was CEG institutional ownership last updated?
The latest CEG 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 CEG 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 CEG position after the reporting date.
Are institutions buying or selling CEG?
Institutional buying and selling can be analyzed by comparing CEG positions across consecutive 13F reporting periods. InsiderSet's CEG Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View CEG ownership changes.
How has CEG institutional ownership changed over time?
