Who are the largest institutional holders of IDA?
The largest institutional holders of IDA reported in the latest SEC Form 13F filings include Blackrock, Inc., Vanguard Portfolio Management Llc, Vanguard Capital Management Llc, Wellington Management Group Llp, and Fmr Llc. InsiderSet ranks institutional holders by their latest reported IDA position.
What is IDA institutional ownership?
This page tracks IDA positions reported by institutional investment managers through SEC Form 13F. IDACORP INC (IDA) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own IDA?
InsiderSet currently tracks 561 institutional managers reporting IDA 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 IDA shareholders.
How much IDA stock do institutions own?
Institutional investment managers disclosed approximately $9.08B in IDA holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was IDA institutional ownership last updated?
The latest IDA 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 IDA 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 IDA position after the reporting date.
Are institutions buying or selling IDA?
Institutional buying and selling can be analyzed by comparing IDA positions across consecutive 13F reporting periods. InsiderSet's IDA Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View IDA ownership changes.
How has IDA institutional ownership changed over time?
InsiderSet tracks IDA institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
