Notable Holders

AIG ranks #384 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

Capital Research Global Investors has trimmed its AIG position for two straight quarters, cutting it by $1.9B while still holding $337.4M.

AIG is up 0.3% today, and institutions have been net buyers of $4.9B this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Smart Money Convergence

AIG 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.
