RARE is trading at $27.89 (9.4% down) in after-hours sessions, retracing gains following a sharp regular-session rally over the past week.
- The move appears to be driven by profit-taking and normal volatility, as there are no clear company-specific catalysts hitting the tape on June 26.
- Broader markets are trading modestly lower, with the biotechnology sector seeing general risk-off sentiment contributing to the downward pressure.
