Who are the largest institutional holders of ENS?
The largest institutional holders of ENS reported in the latest SEC Form 13F filings include Blackrock, Inc., Vanguard Portfolio Management Llc, Vanguard Capital Management Llc, State Street Corp, and Dimensional Fund Advisors Lp. InsiderSet ranks institutional holders by their latest reported ENS position.
What is ENS institutional ownership?
This page tracks ENS positions reported by institutional investment managers through SEC Form 13F. ENERSYS (ENS) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ENS?
InsiderSet currently tracks 534 institutional managers reporting ENS 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 ENS shareholders.
How much ENS stock do institutions own?
Institutional investment managers disclosed approximately $8.25B in ENS holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ENS institutional ownership last updated?
The latest ENS 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 ENS 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 ENS position after the reporting date.
Are institutions buying or selling ENS?
Institutional buying and selling can be analyzed by comparing ENS positions across consecutive 13F reporting periods. InsiderSet's ENS Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View ENS ownership changes.
How has ENS institutional ownership changed over time?
InsiderSet tracks ENS institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
