Questions about Iron Triangle Partners's 13F
What does Iron Triangle Partners own?

Against Q3 2025: 16 new positions, 8 increases, 3 reductions and 14 full exits, from its 13F filings.
How current is this data?
13F filings are due 45 days after each quarter ends, so they show positions at quarter end, not today. The next filing (Q3 2026) is due Nov 16, 2026.
Why are some positions labelled CALL or PUT?
Those are option positions (calls and puts). The 13F reports them as the shares underlying the option, with no strike or expiry, so they are listed apart from share positions.
