Notable Holders

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.

Smart Money Convergence

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.
