Actionable Insight • Neutral

The selling is routine in both dollar amount and as a fraction of market cap. Director Rhodes' sales are likely part of a pre-arranged 10b5-1 plan or portfolio diversification. No insider buying to suggest bullish conviction. Monitor for any material news (e.g., clinical trial updates) that could explain the selling, but the cluster alone does not warrant a bearish read.
