Insider Trading Pulse — July 09, 2026
The July 9, 2026 insider trading pulse reveals a stark divergence between broad-based insider buying at Taiwan Semiconductor Manufacturing Co. (TSMC) and significant insider selling at several US-based growth and healthcare firms. TSMC's CEO and 23 other top executives collectively purchased shares at $76.62, signaling strong management confidence despite a modest aggregate investment of ~$90K. This contrasts sharply with material insider sales at ResMed (CEO sold $1.09M under 10b5-1), Ceribell (CEO sold $469K under 10b5-1), and Pennant Group (CEO sold $128K after exercising cheap options). The day's activity is dominated by TSMC's coordinated insider buying, which represents a powerful vote of confidence in the semiconductor giant's outlook. Meanwhile, several smaller-cap firms saw insider selling that warrants close monitoring for potential headwinds. The data also shows routine option exercises and tax-withholding transactions at First US Bancshares and equity awards at First Northwest Bancorp, which are less informative for directional trading signals.
