What is IESC institutional ownership?
This page tracks IESC positions reported by institutional investment managers through SEC Form 13F. IES HOLDINGS INC (IESC) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own IESC?
InsiderSet currently tracks 414 institutional managers reporting IESC 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 IESC shareholders.
How much IESC stock do institutions own?
Institutional investment managers disclosed approximately $14.04B in IESC holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was IESC institutional ownership last updated?
The latest IESC 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 IESC 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 IESC position after the reporting date.
Are institutions buying or selling IESC?
Institutional buying and selling can be analyzed by comparing IESC positions across consecutive 13F reporting periods. InsiderSet's IESC Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View IESC ownership changes.
How has IESC institutional ownership changed over time?
InsiderSet tracks IESC institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
