Notable Holders

PTEN ranks #1373 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

PTEN is a top-conviction position for Webs Creek Capital Management LP — at 10.2% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in PTEN belongs to BlackRock, Inc., but the position matters far more to Webs Creek Capital Management LP, who has 10.2% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

Blackstone Inc. has trimmed its PTEN position for two straight quarters, cutting it by $152.2M while still holding $19.3M.

Smart Money Convergence

PTEN does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
