The 10b5-1 plan provides a legal shield, but the sustained high-volume selling by a director over five weeks is unusual for a company with strong analyst sentiment. Monitor for any negative catalyst (e.g., FDA setback on Yutrepia or competitive pressure) that could explain the insider's urgency. If the stock breaks below recent support levels, the selling pattern could accelerate.
