Director selling at 0.03% of market cap is routine and not actionable. Monitor for any C-suite insider sales in the next 30 days, which would carry more signal. The convertible note issuance creates potential future dilution but was already priced into the stock.
Price Chart
Executive Summary
Four Amkor directors sold a total of $6.13M in open-market shares over a 7-day window, including $3.71M from one director alone. The cluster follows the company's $1.15B convertible note issuance (May 5), which may have informed the selling. At 0.03% of market cap, the dollar value is trivial and does not signal material insider concern.
Key Financial Metrics
Key Facts
- Four directors sold 81,700 shares total for $6.13M in open-market transactions (May 1-8, 2026)
- Largest sale: Director Guillaume Marie Jean Rutten sold 50,000 shares at $74.28 for $3.71M on May 8
- Total cluster value of $6.13M represents only 0.03% of Amkor's $19.0B market cap
- Cluster occurred 7 days after Amkor issued $1.15B convertible senior notes due 2031 (May 5)
- No C-suite executives participated in the cluster — all sellers are directors
- Prior 30-day insider activity: 5 sells totaling $6.4M, consistent with routine director selling
Financial Impact
$6.13M in open-market sales by directors, negligible relative to $19.0B market cap
Risk Factors
- Convertible note conversion at $106.37/share could dilute equity if stock trades above that level
- No C-suite buying to offset director selling pattern
