Across its top 20 institutional holders, ICLR's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 15/100, avg. turnover score 40/100).
ICLR ranks #1413 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
ICLR is a disclosed holding of Bill Nygren (Harris Associates L.P.), one of the tracked superinvestors on AlphaSMO — it makes up 1.0% of that fund's own 13F portfolio.
ICLR is a top-conviction position for Trinity Street Asset Management 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 ICLR belongs to Artisan Partners Limited Partnership, but the position matters far more to Trinity Street Asset Management 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.
Greenhaven Associates Inc has added to its ICLR position for two straight quarters, increasing it by $535.4M to reach $538.6M today.
Allspring Global Investments Holdings, LLC has trimmed its ICLR position for two straight quarters, cutting it by $196.5M while still holding $7.3M.
ICLR is down 2.2% today, but institutions show net buying of $1.7B this quarter — a divergence between today's price move and the underlying institutional flow.
ICLR posted net income of $42.3M over the trailing twelve months, and currently trades at a P/E of 301.0.

ICLR 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 2026-06-30 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.
