InsiderSet ranks institutional holders by their latest reported PB position.
What is PB institutional ownership?
This page tracks PB positions reported by institutional investment managers through SEC Form 13F. PROSPERITY BANCSHARES INC (PB) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own PB?
InsiderSet currently tracks 460 institutional managers reporting PB 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 PB shareholders.
How much PB stock do institutions own?
Institutional investment managers disclosed approximately $6.51B in PB holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was PB institutional ownership last updated?
The latest PB 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 PB 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 PB position after the reporting date.
Are institutions buying or selling PB?
Institutional buying and selling can be analyzed by comparing PB positions across consecutive 13F reporting periods. InsiderSet's PB Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View PB ownership changes.
How has PB institutional ownership changed over time?
InsiderSet tracks PB institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
