View all 402 holding institutions

Across its top 20 institutional holders, OPEN's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 10/100, avg. turnover score 44/100).

Notable Holders

OPEN ranks #1525 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

OPEN is a top-conviction position for Lennar CORP /new/ — at 99.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in OPEN belongs to California State Teachers Retirement System, but the position matters far more to Lennar CORP /new/, who has 99.0% 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.

Morgan Stanley has added to its OPEN position for two straight quarters, increasing it by $231.5M to reach $532.2M today.

Jim Simons has trimmed its OPEN position for two straight quarters, cutting it by $187.6M while still holding $41.7M.

OPEN is down 5.3% today, but institutions show net buying of $670.4M this quarter — a divergence between today's price move and the underlying institutional flow.

Smart Money Convergence

OPEN 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.
