39 stocks worth $1.49B at Jun 30, 2026, as reported in its 13F, led by SRRK (15.9% of the portfolio). The full list is in the Holdings table above.
Against Q1 2026: 4 new positions, 5 increases, 23 reductions and 0 full exits, from its 13F filings.
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.
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.
