How many institutions own STXS?
InsiderSet currently tracks 110 institutional managers reporting STXS 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 STXS shareholders.

The latest STXS institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
