TSM TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD
Price Chart
Executive Summary
A cluster of insider trades at TSMC shows a VP making small open-market purchases totaling ~$77K while another VP sold $14.0M worth of shares. The sale is material in absolute terms but represents only ~0.0007% of TSMC's $2.1T market cap, making it trivial relative to company size. The purchases are too small to signal conviction, and the sale is likely liquidity-driven given TSMC's massive market cap and the seller's VP role.
Key Financial Metrics
Actionable Insight
This cluster is routine and non-informative. The $14M sale by a VP is trivial relative to TSMC's $2.1T market cap and the small purchases by another VP lack conviction. No trading signal. Monitor TSMC's next earnings release for fundamental updates.
Key Facts
- VP Tien Bor-Zen purchased a total of 1,017 shares for ~$76,698 across three open-market buys on May 19-20, 2026.
- VP Chuang Tzu-Sou sold 200,000 shares for $13.97M in a single open-market sale on May 19, 2026.
- Total cluster value of $14.0M is ~0.0007% of TSMC's $2.1T market cap — well below the 0.1% materiality threshold.
- EVP Mii Yuh-Jier had a non-cash transaction (150,000 shares at $0) on May 22, 2026, which has no economic impact.
- The sale by Chuang Tzu-Sou is large in absolute dollars but routine for a $2.1T company and likely reflects diversification or tax planning, not a bearish signal.
Financial Impact
Total insider sales of $14.0M represent 0.0007% of TSMC's $2.1T market cap — immaterial. Purchases of $77K are negligible.
Risk Factors
- No material insider signal — the cluster does not indicate any change in business outlook.
- The sale could be part of a 10b5-1 plan or routine diversification, not a bearish view.
