What is ACT institutional ownership?
This page tracks ACT positions reported by institutional investment managers through SEC Form 13F. ENACT HOLDINGS INC (ACT) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ACT?
InsiderSet currently tracks 254 institutional managers reporting ACT 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 ACT shareholders.
How much ACT stock do institutions own?
Institutional investment managers disclosed approximately $1.34B in ACT holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ACT institutional ownership last updated?
The latest ACT 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 ACT 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 ACT position after the reporting date.
Are institutions buying or selling ACT?
Institutional buying and selling can be analyzed by comparing ACT positions across consecutive 13F reporting periods. InsiderSet's ACT Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View ACT ownership changes.
How has ACT institutional ownership changed over time?
InsiderSet tracks ACT institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
