What is ASGN institutional ownership?
This page tracks ASGN positions reported by institutional investment managers through SEC Form 13F. ASGN INC (ASGN) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ASGN?
InsiderSet currently tracks 257 institutional managers reporting ASGN 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 ASGN shareholders.
How much ASGN stock do institutions own?
Institutional investment managers disclosed approximately $817.49M in ASGN holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ASGN institutional ownership last updated?
The latest ASGN 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.
