Across its top 20 institutional holders, OIH's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 11/100, avg. turnover score 44/100).
OIH ranks #2304 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
OIH is a disclosed holding of Jane Street (Jane Street Group), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.
OIH is a top-conviction position for Arlington Capital Management, Inc. — at 5.8% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in OIH belongs to Susquehanna International Group, LLP, but the position matters far more to Arlington Capital Management, Inc., who has 5.8% 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.
Columbia Advisory Partners LLC has added to its OIH position for two straight quarters, increasing it by $966.1K to reach $1.2M today.
Banque Pictet & Cie SA has trimmed its OIH position for two straight quarters, cutting it by $5.9M while still holding $2.8M.
OIH is up 0.6% today, and institutions have been net buyers of $457.3M this quarter — today's price move and the underlying institutional flow are pointing the same direction.

OIH 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.
