How many institutions own MTRN?
InsiderSet currently tracks 406 institutional managers reporting MTRN 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 MTRN shareholders.
How much MTRN stock do institutions own?
