The simultaneous $27.2M open-market purchase by a director and a 10% owner at $17/share is a rare and powerful bullish signal. The derivative conversions by LAV and Simeon suggest a restructuring of ownership stakes, possibly ahead of a catalyst. Monitor for upcoming clinical data, partnership, or financing announcement — the insider buying at a fixed price implies confidence in near-term value.
