What is PTEN institutional ownership?
This page tracks PTEN positions reported by institutional investment managers through SEC Form 13F. PATTERSON-UTI ENERGY INC (PTEN) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own PTEN?
InsiderSet currently tracks 429 institutional managers reporting PTEN 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 PTEN shareholders.
How much PTEN stock do institutions own?
Institutional investment managers disclosed approximately $3.89B in PTEN holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was PTEN institutional ownership last updated?
The latest PTEN 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 PTEN 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 PTEN position after the reporting date.
Are institutions buying or selling PTEN?
Institutional buying and selling can be analyzed by comparing PTEN positions across consecutive 13F reporting periods. InsiderSet's PTEN Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View PTEN ownership changes.
How has PTEN institutional ownership changed over time?
