Frequently asked questions about SIGI
Who are the largest institutional holders of SIGI?
The largest institutional holders of SIGI reported in the latest SEC Form 13F filings include Blackrock, Inc., Vanguard Portfolio Management Llc, Aqr Capital Management Llc, Vanguard Capital Management Llc, and State Street Corp. InsiderSet ranks institutional holders by their latest reported SIGI position.
What is SIGI institutional ownership?
This page tracks SIGI positions reported by institutional investment managers through SEC Form 13F. SELECTIVE INSURANCE GROUP (SIGI) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own SIGI?
InsiderSet currently tracks 370 institutional managers reporting SIGI 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 SIGI shareholders.
How much SIGI stock do institutions own?
Institutional investment managers disclosed approximately $5.02B in SIGI holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was SIGI institutional ownership last updated?
The latest SIGI 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 SIGI 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 SIGI position after the reporting date.
Are institutions buying or selling SIGI?
Institutional buying and selling can be analyzed by comparing SIGI positions across consecutive 13F reporting periods. InsiderSet's SIGI Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View SIGI ownership changes.
How has SIGI institutional ownership changed over time?
InsiderSet tracks SIGI institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
