What is MOG-B institutional ownership?
This page tracks MOG-B positions reported by institutional investment managers through SEC Form 13F. MOOG INC-CLASS B (MOG-B) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own MOG-B?
InsiderSet currently tracks 21 institutional managers reporting MOG-B 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 MOG-B shareholders.
How much MOG-B stock do institutions own?
