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.

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 2026-06-30 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.
