Frequently asked questions about AA
Who are the largest institutional holders of AA?
The largest institutional holders of AA reported in the latest SEC Form 13F filings include Blackrock, Inc., Fmr Llc, Vanguard Portfolio Management Llc, Vanguard Capital Management Llc, and Eagle Capital Management. InsiderSet ranks institutional holders by their latest reported AA position.
What is AA institutional ownership?
This page tracks AA positions reported by institutional investment managers through SEC Form 13F. ALCOA CORP (AA) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own AA?
InsiderSet currently tracks 667 institutional managers reporting AA 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 AA shareholders.
How much AA stock do institutions own?
Institutional investment managers disclosed approximately $10.35B in AA holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was AA institutional ownership last updated?
The latest AA 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 AA 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 AA position after the reporting date.
Are institutions buying or selling AA?
Institutional buying and selling can be analyzed by comparing AA positions across consecutive 13F reporting periods. InsiderSet's AA Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View AA ownership changes.
How has AA institutional ownership changed over time?
InsiderSet tracks AA institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
