Across its top 20 institutional holders, SPY's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 25/100, avg. turnover score 47/100).
SPY ranks #11 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

SPY is a top-conviction position for RK Capital Management, LLC/FL — at 66.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in SPY belongs to Jane Street Group, LLC, but the position matters far more to RK Capital Management, LLC/FL, who has 66.0% 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.
Jane Street Group, LLC has added to its SPY position for two straight quarters, increasing it by $107.6B to reach $203.5B today.
BlackRock has trimmed its SPY position for two straight quarters, cutting it by $9.5B while still holding $12.3B.

SPY 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.
