The cluster is dominated by two large trims from Dimensional and Assenagon, but the insider buying of nearly $1M suggests management sees value. Monitor upcoming Q3 earnings and any pipeline catalysts (e.g., clinical data) to see if the selling was thesis-driven or portfolio rebalancing.
How similar events traded
Executive Summary
A small institutional cluster in RGNX shows mixed conviction: three asset managers added tiny positions (total $276K) while Dimensional Fund Advisors and Assenagon Asset Management trimmed $8.5M in aggregate. The net selling is dominant in dollar terms, but the insider buying ($949K open-market) provides a partial offset. The cluster is too small in scale to signal a strong directional thesis.
