Insider selling is consistent across multiple insiders but modest relative to market cap — the selling is likely not a material signal of deterioration. However, the persistent lack of insider buying and the company's poor historical stock response to prior reports (avg T+20 alpha -6%) suggest continued weakness. Monitor for any negative pipeline updates or upcoming financing events.
