No actionable signal—the insider activity is de minimis and reflects a routine executive stock purchase plan. Monitor upcoming earnings or guidance for any material fundamental changes, but this cluster offers no edge.
Price Chart
Executive Summary
A cluster of 31 TSMC insiders executed trades over a 7-day window, with 30 executives making open-market purchases totaling ~$117K and one controller selling $4K. The CEO and CFO both participated in the buying, but the aggregate dollar value is negligible relative to TSMC's $2.18T market cap (0.0000055%). This is a routine, coordinated purchase plan—likely a dividend reinvestment or stock purchase program—and carries no material signal.
Key Financial Metrics
Key Facts
- 30 senior executives (including CEO, CFO, Co-COOs, and multiple SVPs/VPs) each bought small lots of shares on July 7, 2026, all at $76.62.
- Total cluster value: ~$121K (buys ~$117K, sell ~$4K).
- CEO Wei Che-Chia bought 146 shares (~$11K); CFO Huang Jen-Chau bought 28 shares (~$2K).
- Controller Chen Chih-Ho sold 50 shares on July 14 but had bought 50 shares the day prior—a net neutral position.
- Total value is <0.001% of TSMC's $2.18T market cap—trivial and routine.
Financial Impact
~$121K total insider trading value, which is immaterial for a $2.18T company.
Risk Factors
- Insider purchases are too small to indicate confidence in near-term upside.
- Coordinated purchases on a single date may simply be a pre-arranged plan, not discretionary.
