As of Q2 2026, 30 SEC-registered investment managers reported holding RGNX (REGENXBIO INC) in their latest 13F filings, with a combined reported value of $254.44M across 21.33M shares. That is +32.8% by share count (+5.27M shares) versus the previous quarter, while reported value moved +89.7%. Ownership is concentrated: the five largest holders account for 62.8% of reported value and the top ten for 83.6%.

Compared with the prior quarter, 3 opened new positions, 19 added to existing stakes, 8 trimmed, 2 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

RGNX 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.
