Frequently asked questions about PTEN activity

  • Which institutional owners are buying PTEN?

The activity table above highlights which funds added shares in the latest reporting periods and how their positions changed over time.

  • What does "buy" mean in PTEN activity?

    "Buy" means an investor increased their reported position in PTEN compared to the prior reporting period. This reflects growing exposure to PATTERSON-UTI ENERGY INC (PTEN) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).

  • Is institutional interest in PTEN increasing?
