What does the MCO superinvestors page include?
This page tracks MCO positions reported by a curated group of notable institutional investors and fund managers through SEC Form 13F. MOODY'S CORP (MCO) on this page reflects disclosed 13F holdings among those superinvestors, not every institutional shareholder of the stock.
How many superinvestors hold MCO?
InsiderSet currently tracks 19 superinvestors reporting MCO holdings in the latest available 13F data. This is the curated set on this page, not the total number of institutions that own MCO.
How much MCO stock do superinvestors hold?
Superinvestors tracked by InsiderSet disclosed approximately $19.99B in MCO holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value, and it covers the curated superinvestors on this page rather than every institutional filer.
When were MCO superinvestor holdings last updated?
The latest MCO superinvestor holdings on InsiderSet are 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 holdings.
Are superinvestor MCO holdings real-time?
No. Form 13F data is not real-time. It represents positions reported by these superinvestors as of the end of the reporting quarter. A superinvestor may have changed its MCO position after the reporting date.
Are superinvestors buying or selling MCO?
Buying and selling can be analyzed by comparing MCO positions across consecutive 13F reporting periods. InsiderSet's MCO Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View MCO ownership changes.
How have superinvestor MCO holdings changed over time?
InsiderSet tracks MCO holdings among these superinvestors across multiple 13F reporting periods, so holder counts, reported value, and reported shares can be compared over time.
