What it reported after the quarter end (Q2 2026)
The 13F shows the portfolio as of Jun 30, 2026. Since then Rush Island Management has filed these own trades with the SEC (Form 4, when it owns more than 10% of a company or holds a role in it) and stakes above 5% (13D and 13G). It is not everything it did: only what it must report before the next 13F.
