What is RCUS institutional ownership?
This page tracks RCUS positions reported by institutional investment managers through SEC Form 13F. ARCUS BIOSCIENCES INC (RCUS) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own RCUS?
InsiderSet currently tracks 224 institutional managers reporting RCUS 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 RCUS shareholders.
How much RCUS stock do institutions own?
Institutional investment managers disclosed approximately $3.78B in RCUS holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was RCUS institutional ownership last updated?
The latest RCUS 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 RCUS 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 RCUS position after the reporting date.
