What is ADEA institutional ownership?
This page tracks ADEA positions reported by institutional investment managers through SEC Form 13F. ADEIA INC (ADEA) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ADEA?
InsiderSet currently tracks 289 institutional managers reporting ADEA 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 ADEA shareholders.
How much ADEA stock do institutions own?
Institutional investment managers disclosed approximately $3.35B in ADEA holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ADEA institutional ownership last updated?
The latest ADEA 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 ADEA holdings real-time?
