Smart Money Convergence

PAGP 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 2026-09-30 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.
