What is SSD institutional ownership?
This page tracks SSD positions reported by institutional investment managers through SEC Form 13F. SIMPSON MANUFACTURING CO INC (SSD) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own SSD?
InsiderSet currently tracks 475 institutional managers reporting SSD 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 SSD shareholders.
How much SSD stock do institutions own?
Institutional investment managers disclosed approximately $8.50B in SSD holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was SSD institutional ownership last updated?
The latest SSD 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 SSD 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 SSD position after the reporting date.
Are institutions buying or selling SSD?
Institutional buying and selling can be analyzed by comparing SSD positions across consecutive 13F reporting periods. InsiderSet's SSD Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View SSD ownership changes.
How has SSD institutional ownership changed over time?
InsiderSet tracks SSD institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
