The cluster of large insider sales at ~$75/share is a notable supply overhang. Monitor for additional filings (e.g., Form 144s) and any material news (earnings, M&A) that might explain the selling. The absence of insider buying and the pattern of derivative conversions followed by immediate sales warrants caution.
Price Chart
Executive Summary
