AMSC AMERICAN SUPERCONDUCTOR CORP /DE/
Price Chart
Executive Summary
CEO Daniel McGahn and CFO John Kosiba sold a combined $772K of AMSC stock at $37-41/share over three open-market trades in early June 2026. The CEO's two sales spanned a 15% price decline, suggesting profit-taking or liquidity-driven selling rather than a coordinated bearish signal. At $1.8B market cap, the cluster is <0.1% of float — well below the materiality threshold for insider sales.
Key Financial Metrics
Actionable Insight
Insider sales are <0.1% of market cap and too small to signal fundamental deterioration. The CEO selling into a 15% pullback from June 8 to June 11 is characteristic of profit-taking or tax-planning, not informed selling. Monitor next quarterly earnings for growth trajectory, but this cluster alone does not warrant a trade.
Key Facts
- CEO McGahn sold 16,500 shares for $635,661 across two trades on June 8 and June 11, 2026
- CFO Kosiba sold 3,288 shares for $136,371 on June 8, 2026
- Total cluster value of ~$772K represents 0.04% of AMSC's $1.8B market cap
- CEO's June 11 sale at $37.28 is a 10% discount from his June 8 sale at $41.39 — no pattern suggesting a single predetermined price target
- Non-cash transactions within cluster were not detected
Financial Impact
Executive sales totaling $772K — immaterial relative to $1.8B market cap
Risk Factors
- CEO sold 40% more shares on the second trade after a 10% price drop — may indicate growing bearishness if pattern continues
- 90% of sell-side analysts rate the stock Buy, but the CEO's selling may be viewed negatively by momentum traders
