What is MSLE institutional ownership?
This page tracks MSLE positions reported by institutional investment managers through SEC Form 13F. SATELLOS BIOSCIENCE INC (MSLE) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own MSLE?
InsiderSet currently tracks 26 institutional managers reporting MSLE 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 MSLE shareholders.
How much MSLE stock do institutions own?
Institutional investment managers disclosed approximately $52.31M in MSLE holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was MSLE institutional ownership last updated?
The latest MSLE institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026. Form 13F filings are generally reported after the quarter ends, so the holdings shown represent the latest publicly disclosed positions rather than real-time institutional holdings.
Are institutional MSLE holdings real-time?
No. Form 13F data is not real-time. It represents positions reported by institutional investment managers as of the end of the reporting quarter. An institution may have changed its MSLE position after the reporting date.
Are institutions buying or selling MSLE?
Institutional buying and selling can be analyzed by comparing MSLE positions across consecutive 13F reporting periods. InsiderSet's MSLE Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View MSLE ownership changes.
