Across its top 20 institutional holders, SEI's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 12/100, avg. turnover score 46/100).
SEI ranks #1403 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
SEI is a top-conviction position for Encompass Capital Advisors LLC — at 7.2% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in SEI belongs to BlackRock, Inc., but the position matters far more to Encompass Capital Advisors LLC, who has 7.2% 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.
BlackRock has added to its SEI position for two straight quarters, increasing it by $220.5M to reach $418.7M today.
Summit Partners Public Asset Management, LLC has trimmed its SEI position for two straight quarters, cutting it by $31.0M while still holding $136.2M.
SEI is down 5.6% today, but institutions show net buying of $1.0B this quarter — a divergence between today's price move and the underlying institutional flow.
SEI posted net income of $54.8M over the trailing twelve months, and currently trades at a P/E of 45.1.

Top 5 Institutional Movers
SEI 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.
