As of Q2 2026, 40 SEC-registered investment managers reported holding PTCT (PTC THERAPEUTICS INC) in their latest 13F filings, with a combined reported value of $2.73B across 40.00M shares. That is -24.0% by share count (-12.65M shares) versus the previous quarter, while reported value moved +40.2%.

Compared with the prior quarter, 3 opened new positions, 19 added to existing stakes, 16 trimmed, 1 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

PTCT is classified in the Health Care sector.

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.
