View all 1277 holding institutions

Across its top 20 institutional holders, AON's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 6/100, avg. turnover score 31/100).

Notable Holders

AON ranks #329 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

AON is a top-conviction position for Veritas Asset Management LLP — at 8.4% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in AON belongs to BlackRock, Inc., but the position matters far more to Veritas Asset Management LLP, who has 8.4% 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.

Concurrent Investment Advisors, LLC has added to its AON position for two straight quarters, increasing it by $764.8K to reach $2.4M today.

Sustainable Growth Advisers, LP has trimmed its AON position for two straight quarters, cutting it by $293.4M while still holding $46.1M.

AON is up 2% today, and institutions have been net buyers of $24.3B this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Smart Money Convergence

AON does not currently show a 13F-and-insider convergence signal — its insider confidence score is 46/100, below the threshold this product uses to flag combined buying pressure.

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.
