Who are the largest institutional holders of O?
The largest institutional holders of O reported in the latest SEC Form 13F filings include Blackrock, Inc., Vanguard Portfolio Management Llc, State Street Corp, Vanguard Capital Management Llc, and Geode Capital Management, Llc. InsiderSet ranks institutional holders by their latest reported O position.
What is O institutional ownership?
This page tracks O positions reported by institutional investment managers through SEC Form 13F. REALTY INCOME CORP (O) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own O?
InsiderSet currently tracks 1,428 institutional managers reporting O 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 O shareholders.
How much O stock do institutions own?
Institutional investment managers disclosed approximately $43.92B in O holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was O institutional ownership last updated?
The latest O 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 O 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 O position after the reporting date.
Are institutions buying or selling O?
Institutional buying and selling can be analyzed by comparing O positions across consecutive 13F reporting periods. InsiderSet's O Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View O ownership changes.
How has O institutional ownership changed over time?
InsiderSet tracks O institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
