Across its top 20 institutional holders, OSS's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 6/100, avg. turnover score 34/100).
OSS ranks #4321 out of 37501 tracked stocks by institutional interest, inside the more closely watched half of our coverage.
OSS 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.
113 institutions disclose a position in OSS, but none treat it as a major bet — even Palisades Investment Partners, LLC, its most concentrated holder, allocates just 2.1% of its own portfolio to it.
BlackRock has added to its OSS position for two straight quarters, increasing it by $32.4M to reach $33.4M today.
Thompson Siegel & Walmsley LLC has trimmed its OSS position for two straight quarters, cutting it by $521.0K while still holding $578.0K.
OSS is down 4.3% today, but institutions show net buying of $88.7M this quarter — a divergence between today's price move and the underlying institutional flow.

Top 5 Institutional Movers
OSS 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.
