ALKS Alkermes plc.
Price Chart
Executive Summary
Three Alkermes insiders, including the EVP R&D/CMO and VP Finance, sold a total of ~$1.15M in open-market sales over a 7-day window. The sales are modest relative to the $7.1B market cap (~0.016%) and include derivative exercises that likely generated shares for sale. No insider buying occurred. The cluster is small in dollar terms and likely reflects routine portfolio diversification and tax-related selling rather than a coordinated bearish signal.
Key Financial Metrics
Actionable Insight
Insider selling is small and routine — no actionable signal. Monitor for any material corporate events (earnings, pipeline updates, M&A) that could trigger more significant insider activity. The historical win rate on ALKS reports is strong (63% at T+20), but this cluster lacks the dollar magnitude to be predictive.
Key Facts
