What is ARQ institutional ownership?
This page tracks ARQ positions reported by institutional investment managers through SEC Form 13F. ARQ INC (ARQ) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ARQ?
InsiderSet currently tracks 94 institutional managers reporting ARQ 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 ARQ shareholders.
How much ARQ stock do institutions own?
Institutional investment managers disclosed approximately $35.19M in ARQ holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ARQ institutional ownership last updated?
The latest ARQ 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 ARQ 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 ARQ position after the reporting date.
Are institutions buying or selling ARQ?
Institutional buying and selling can be analyzed by comparing ARQ positions across consecutive 13F reporting periods. InsiderSet's ARQ Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View ARQ ownership changes.
How has ARQ institutional ownership changed over time?
InsiderSet tracks ARQ institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
