What is BLDR institutional ownership?
This page tracks BLDR positions reported by institutional investment managers through SEC Form 13F. BUILDERS FIRSTSOURCE INC (BLDR) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own BLDR?
InsiderSet currently tracks 640 institutional managers reporting BLDR 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 BLDR shareholders.
How much BLDR stock do institutions own?
Institutional investment managers disclosed approximately $9.50B in BLDR holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was BLDR institutional ownership last updated?
The latest BLDR 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 BLDR 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 BLDR position after the reporting date.
Are institutions buying or selling BLDR?
Institutional buying and selling can be analyzed by comparing BLDR positions across consecutive 13F reporting periods. InsiderSet's BLDR Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View BLDR ownership changes.
How has BLDR institutional ownership changed over time?
