What is TBT institutional ownership?
This page tracks TBT positions reported by institutional investment managers through SEC Form 13F. PROSHARES ULTRASHORT 20+Y TR (TBT) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own TBT?
InsiderSet currently tracks 59 institutional managers reporting TBT 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 TBT shareholders.
How much TBT stock do institutions own?
Institutional investment managers disclosed approximately $87.51M in TBT holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was TBT institutional ownership last updated?
The latest TBT 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 TBT 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 TBT position after the reporting date.
Are institutions buying or selling TBT?
Institutional buying and selling can be analyzed by comparing TBT positions across consecutive 13F reporting periods. InsiderSet's TBT Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View TBT ownership changes.
