What is OMEX institutional ownership?
This page tracks OMEX positions reported by institutional investment managers through SEC Form 13F. ODYSSEY MARINE EXPLORATION (OMEX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own OMEX?
InsiderSet currently tracks 57 institutional managers reporting OMEX 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 OMEX shareholders.
How much OMEX stock do institutions own?
Institutional investment managers disclosed approximately $16.33M in OMEX holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was OMEX institutional ownership last updated?
The latest OMEX 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 OMEX 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 OMEX position after the reporting date.
Are institutions buying or selling OMEX?
Institutional buying and selling can be analyzed by comparing OMEX positions across consecutive 13F reporting periods. InsiderSet's OMEX Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View OMEX ownership changes.
