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 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
SPY is a disclosed holding of Jane Street (Jane Street Group), one of the tracked superinvestors on AlphaSMO — it makes up 16.9% of that fund's own 13F portfolio.
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.
DAVENPORT & Co LLC has added to its SPY position for two straight quarters, increasing it by $215.6M to reach $387.6M today.
Two Seas Capital LP has trimmed its SPY position for two straight quarters, cutting it by $3.1B while still holding $1.1B.
SPY is down 1.1% today, but institutions show net buying of $145.4B this quarter — a divergence between today's price move and the underlying institutional flow.

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 2026-09-30 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.
