The largest institutional holders of AROC reported in the latest SEC Form 13F filings include Blackrock, Inc., Vanguard Portfolio Management Llc, Earnest Partners Llc, Vanguard Capital Management Llc, and State Street Corp. InsiderSet ranks institutional holders by their latest reported AROC position.
What is AROC institutional ownership?
This page tracks AROC positions reported by institutional investment managers through SEC Form 13F. ARCHROCK INC (AROC) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own AROC?
InsiderSet currently tracks 432 institutional managers reporting AROC 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 AROC shareholders.
How much AROC stock do institutions own?
Institutional investment managers disclosed approximately $6.65B in AROC holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was AROC institutional ownership last updated?
The latest AROC 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 AROC 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 AROC position after the reporting date.
Are institutions buying or selling AROC?
Institutional buying and selling can be analyzed by comparing AROC positions across consecutive 13F reporting periods. InsiderSet's AROC Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View AROC ownership changes.
How has AROC institutional ownership changed over time?
InsiderSet tracks AROC institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
