The near-unanimous institutional selling, especially Citadel's near-exit, is a strong bearish signal for OSG. Monitor for any Q4 2025 13F filings to see if selling continued or reversed. The stock's small $251M market cap means these $10.1M in outflows represent ~4% of market cap — material for a thinly traded name.
Executive Summary
Four major institutional investors — D.E. Shaw, Morgan Stanley, Citadel, and RenTech — collectively reduced their OSG positions by $10.1M in Q3 2025, while only T. Rowe Price added a trivial $221.

Risk Factors
- 13F data has a 45-day lag; positions may have been reversed since quarter-end
- The cluster is dominated by quant funds (D.E. Shaw, Citadel, RenTech) whose systematic strategies may not reflect fundamental views
- T. Rowe Price's small add could be passive rebalancing, not conviction
