Notable Holders

AJG ranks #315 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

AJG is a top-conviction position for Gtcr LLC — at 13.9% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in AJG belongs to BlackRock, Inc., but the position matters far more to Gtcr LLC, who has 13.9% 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.

Dodge & Cox has added to its AJG position for two straight quarters, increasing it by $1.9B to reach $2.1B today.

JPMorgan has trimmed its AJG position for two straight quarters, cutting it by $2.0B while still holding $3.3B.

AJG is up 0.9% today, and institutions have been net buyers of $16.7B this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Smart Money Convergence

AJG does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.

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.
