How many institutions own JSPR?
InsiderSet currently tracks 45 institutional managers reporting JSPR 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 JSPR shareholders.

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