What is CATX institutional ownership?
This page tracks CATX positions reported by institutional investment managers through SEC Form 13F. PERSPECTIVE THERAPEUTICS INC (CATX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own CATX?
InsiderSet currently tracks 118 institutional managers reporting CATX 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 CATX shareholders.
How much CATX stock do institutions own?

When was CATX institutional ownership last updated?
The latest CATX institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
