What is ALSN institutional ownership?
This page tracks ALSN positions reported by institutional investment managers through SEC Form 13F. ALLISON TRANSMISSION HOLDING (ALSN) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ALSN?
InsiderSet currently tracks 576 institutional managers reporting ALSN 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 ALSN shareholders.
How much ALSN stock do institutions own?
Institutional investment managers disclosed approximately $9.58B in ALSN holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ALSN institutional ownership last updated?
The latest ALSN 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 ALSN 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 ALSN position after the reporting date.
Are institutions buying or selling ALSN?
