Who are the largest institutional holders of SR?
The largest institutional holders of SR reported in the latest SEC Form 13F filings include Blackrock, Inc., Vanguard Portfolio Management Llc, State Street Corp, Vanguard Capital Management Llc, and American Century Companies Inc. InsiderSet ranks institutional holders by their latest reported SR position.
What is SR institutional ownership?
This page tracks SR positions reported by institutional investment managers through SEC Form 13F. SPIRE INC (SR) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own SR?
InsiderSet currently tracks 399 institutional managers reporting SR 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 SR shareholders.
How much SR stock do institutions own?
Institutional investment managers disclosed approximately $4.12B in SR holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was SR institutional ownership last updated?
The latest SR 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 SR 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 SR position after the reporting date.
Are institutions buying or selling SR?
Institutional buying and selling can be analyzed by comparing SR positions across consecutive 13F reporting periods. InsiderSet's SR Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View SR ownership changes.
How has SR institutional ownership changed over time?
InsiderSet tracks SR institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
