Across its top 20 institutional holders, ACGL's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 9/100, avg. turnover score 41/100).
ACGL ranks #545 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
ACGL is a top-conviction position for High Ground Investment Management LLP — at 22.3% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in ACGL belongs to BlackRock, Inc., but the position matters far more to High Ground Investment Management LLP, who has 22.3% 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.
Gateway Investment Advisers LLC has added to its ACGL position for two straight quarters, increasing it by $1.5M to reach $2.5M today.
Confluence Investment Management LLC has trimmed its ACGL position for two straight quarters, cutting it by $5.8M while still holding $29.1M.
ACGL is up 2% today, and institutions have been net buyers of $4.1B this quarter — today's price move and the underlying institutional flow are pointing the same direction.
ACGL posted net income of $4.7B over the trailing twelve months, and currently trades at a P/E of 8.1.

ACGL 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 2026-09-30 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.
