What is MDIA institutional ownership?
This page tracks MDIA positions reported by institutional investment managers through SEC Form 13F. MEDIACO HOLDING INC-CL A (MDIA) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own MDIA?
InsiderSet currently tracks 18 institutional managers reporting MDIA 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 MDIA shareholders.
How much MDIA stock do institutions own?
InsiderSet aggregates disclosed MDIA position values from SEC Form 13F filings for the latest available reporting period. Figures on this page are reported 13F value, not necessarily today's market value.
When was MDIA institutional ownership last updated?
The latest MDIA 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 MDIA 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 MDIA position after the reporting date.
Are institutions buying or selling MDIA?
Institutional buying and selling can be analyzed by comparing MDIA positions across consecutive 13F reporting periods. InsiderSet's MDIA Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View MDIA ownership changes.
How has MDIA institutional ownership changed over time?
InsiderSet tracks MDIA institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
