The largest institutional holders of ASX reported in the latest SEC Form 13F filings include Banque Cantonale Vaudoise, Blackrock, Inc., Bank Of America Corp, Goldman Sachs Group Inc, and Lazard Asset Management Llc. InsiderSet ranks institutional holders by their latest reported ASX position.
What is ASX institutional ownership?
This page tracks ASX positions reported by institutional investment managers through SEC Form 13F. ASE TECHNOLOGY HOLDING -ADR (ASX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own ASX?
InsiderSet currently tracks 487 institutional managers reporting ASX 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 ASX shareholders.
How much ASX stock do institutions own?
Institutional investment managers disclosed approximately $9.46B in ASX holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was ASX institutional ownership last updated?
The latest ASX 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 ASX 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 ASX position after the reporting date.
Are institutions buying or selling ASX?
Institutional buying and selling can be analyzed by comparing ASX positions across consecutive 13F reporting periods. InsiderSet's ASX Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View ASX ownership changes.
How has ASX institutional ownership changed over time?
InsiderSet tracks ASX institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
