Who are the largest institutional holders of MOS?
The largest institutional holders of MOS reported in the latest SEC Form 13F filings include Blackrock, Inc., Vanguard Capital Management Llc, Aqr Capital Management Llc, State Street Corp, and Invesco Ltd.. InsiderSet ranks institutional holders by their latest reported MOS position.
What is MOS institutional ownership?
This page tracks MOS positions reported by institutional investment managers through SEC Form 13F. MOSAIC CO/THE (MOS) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own MOS?
InsiderSet currently tracks 660 institutional managers reporting MOS 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 MOS shareholders.
How much MOS stock do institutions own?
Institutional investment managers disclosed approximately $6.56B in MOS holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was MOS institutional ownership last updated?
The latest MOS 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 MOS 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 MOS position after the reporting date.
Are institutions buying or selling MOS?
Institutional buying and selling can be analyzed by comparing MOS positions across consecutive 13F reporting periods. InsiderSet's MOS Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View MOS ownership changes.
How has MOS institutional ownership changed over time?
InsiderSet tracks MOS institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
