Who are the largest institutional holders of DCO?
The largest institutional holders of DCO reported in the latest SEC Form 13F filings include Blackrock, Inc., State Street Corp, Fmr Llc, Paradigm Capital Management Inc/Ny, and Vanguard Capital Management Llc. InsiderSet ranks institutional holders by their latest reported DCO position.
What is DCO institutional ownership?
This page tracks DCO positions reported by institutional investment managers through SEC Form 13F. DUCOMMUN INC (DCO) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own DCO?
InsiderSet currently tracks 267 institutional managers reporting DCO 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 DCO shareholders.
How much DCO stock do institutions own?
Institutional investment managers disclosed approximately $2.64B in DCO holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was DCO institutional ownership last updated?
The latest DCO 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 DCO 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 DCO position after the reporting date.
Are institutions buying or selling DCO?
Institutional buying and selling can be analyzed by comparing DCO positions across consecutive 13F reporting periods. InsiderSet's DCO Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View DCO ownership changes.
How has DCO institutional ownership changed over time?
InsiderSet tracks DCO institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
