Notable Holders

CNM ranks #1317 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

CNM is a top-conviction position for Camrose Capital Investment Partners LLP — at 13.7% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in CNM belongs to BlackRock, Inc., but the position matters far more to Camrose Capital Investment Partners LLP, who has 13.7% 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 CNM position for two straight quarters, increasing it by $2.7M to reach $3.1M today.

Assenagon Asset Management S.A. has trimmed its CNM position for two straight quarters, cutting it by $42.2M while still holding $3.8M.

CNM is up 0.5% today, and institutions have been net buyers of $1.1B this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Smart Money Convergence

CNM does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

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.
