TSM TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD
Price Chart
Executive Summary
Five TSM insiders, including EVP/Co-COO Chin Yung-Pei and three VPs, made open-market purchases totaling ~$19.5K on June 5, 2026. While the dollar amount is trivial relative to TSM's $2.2T market cap, the cluster of C-suite and senior VP buys is a rare signal of conviction at a company where insider buying is infrequent. The historical win rate on TSM reports is 100% at T+20, and cross-filing amplifiers suggest this cluster may carry more weight than the raw dollar value implies.
Key Financial Metrics
Actionable Insight
The cluster of senior insiders buying simultaneously is a rare signal of confidence, but the dollar amount is too small to move the stock. Monitor for any upcoming material announcements (earnings, capex updates, or geopolitical developments) that may have prompted the coordinated purchases. The 100% historical win rate on TSM reports at T+20 suggests the stock may continue its upward trend, but this filing alone does not justify a position change.

Financial Impact
~$19.5K in insider purchases, negligible relative to $2.2T market cap

- No accompanying material corporate event in the filing to explain the cluster
