As of Q2 2026, 38 SEC-registered investment managers reported holding CPRX (CATALYST PHARMACEUTICALS INC) in their latest 13F filings, with a combined reported value of $1.42B across 45.25M shares. That is -3.5% by share count (-1.66M shares) versus the previous quarter, while reported value moved +24.1%. Ownership is concentrated: the five largest holders account for 67.4% of reported value and the top ten for 81.7%.
Compared with the prior quarter, 4 opened new positions, 19 added to existing stakes, 14 trimmed, 3 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.
All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
