Across its top 20 institutional holders, BLK's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 6/100, avg. turnover score 33/100).
BLK ranks #106 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
BLK is a top-conviction position for Temasek Holdings — at 13.4% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in BLK belongs to BlackRock, Inc., but the position matters far more to Temasek Holdings, who has 13.4% 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.
Assenagon Asset Management S.A. has added to its BLK position for two straight quarters, increasing it by $126.4M to reach $238.9M today.
Fjarde Ap-fonden /fourth Swedish National Pension Fund has trimmed its BLK position for two straight quarters, cutting it by $16.6M while still holding $34.9M.
BLK is up 1.2% today, and institutions have been net buyers of $77.1B this quarter — today's price move and the underlying institutional flow are pointing the same direction.
BLK posted net income of $6.6B over the trailing twelve months, and currently trades at a P/E of 27.7.

BLK 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.
