What is COGT institutional ownership?
This page tracks COGT positions reported by institutional investment managers through SEC Form 13F. COGENT BIOSCIENCES INC (COGT) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own COGT?
InsiderSet currently tracks 309 institutional managers reporting COGT 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 COGT shareholders.
How much COGT stock do institutions own?
Institutional investment managers disclosed approximately $7.42B in COGT holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was COGT institutional ownership last updated?
The latest COGT institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
