TSM TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD
Price Chart
Executive Summary
A cluster of 16 TSMC insiders, including the CFO, Deputy Co-COO, and multiple VPs, made open-market purchases totaling ~$60K on June 5, 2026, at $76.01 per share. While the dollar amount is trivial relative to TSMC's $2.2T market cap, the breadth of C-suite and senior VP participation is a rare and notable signal of confidence in the company's near-term outlook. The cluster is amplified by a strong historical win rate on TSM reports and statistically significant cross-filing amplifier verdicts.
