What is ACTG institutional ownership?
This page tracks ACTG positions reported by institutional investment managers through SEC Form 13F. ACACIA RESEARCH CORP (ACTG) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ACTG?
InsiderSet currently tracks 121 institutional managers reporting ACTG 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 ACTG shareholders.
How much ACTG stock do institutions own?

When was ACTG institutional ownership last updated?
The latest ACTG 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 ACTG 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 ACTG position after the reporting date.
