What is MDU institutional ownership?
This page tracks MDU positions reported by institutional investment managers through SEC Form 13F. MDU RESOURCES GROUP INC (MDU) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own MDU?
InsiderSet currently tracks 421 institutional managers reporting MDU 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 MDU shareholders.
How much MDU stock do institutions own?
Institutional investment managers disclosed approximately $4.03B in MDU holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was MDU institutional ownership last updated?
The latest MDU 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 MDU 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 MDU position after the reporting date.
Are institutions buying or selling MDU?
Institutional buying and selling can be analyzed by comparing MDU positions across consecutive 13F reporting periods. InsiderSet's MDU Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View MDU ownership changes.
