InsiderSet ranks institutional holders by their latest reported GRC position.
What is GRC institutional ownership?
This page tracks GRC positions reported by institutional investment managers through SEC Form 13F. GORMAN-RUPP CO (GRC) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own GRC?
InsiderSet currently tracks 236 institutional managers reporting GRC 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 GRC shareholders.
How much GRC stock do institutions own?
Institutional investment managers disclosed approximately $1.46B in GRC holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was GRC institutional ownership last updated?
The latest GRC 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 GRC 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 GRC position after the reporting date.
Are institutions buying or selling GRC?
Institutional buying and selling can be analyzed by comparing GRC positions across consecutive 13F reporting periods. InsiderSet's GRC Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View GRC ownership changes.
How has GRC institutional ownership changed over time?
InsiderSet tracks GRC institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
