How many institutions own TDUP?
InsiderSet currently tracks 175 institutional managers reporting TDUP 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 TDUP shareholders.
