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 #4325 out of 37696 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.

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 2026-09-30 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.
