How many institutions own LUNG?
InsiderSet currently tracks 104 institutional managers reporting LUNG 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 LUNG shareholders.
