The largest institutional holders of SW reported in the latest SEC Form 13F filings include Blackrock, Inc., Capital Research Global Investors, Vanguard Capital Management Llc, State Street Corp, and Nuveen, Llc. InsiderSet ranks institutional holders by their latest reported SW position.
What is SW institutional ownership?
This page tracks SW positions reported by institutional investment managers through SEC Form 13F. SMURFIT WESTROCK PLC (SW) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own SW?
InsiderSet currently tracks 655 institutional managers reporting SW 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 SW shareholders.
How much SW stock do institutions own?
Institutional investment managers disclosed approximately $22.41B in SW holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was SW institutional ownership last updated?
The latest SW 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 SW 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 SW position after the reporting date.
Are institutions buying or selling SW?
Institutional buying and selling can be analyzed by comparing SW positions across consecutive 13F reporting periods. InsiderSet's SW Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View SW ownership changes.
How has SW institutional ownership changed over time?
InsiderSet tracks SW institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
