Director NACHTSHEIM JAMI K sold 2,400 shares of ISRG at $520.00 on 2025-05-01; retained 6,371 shares post-sale.
Director JAMI K NACHTSHEIM sold 2,400 shares (27.4% of pre-transaction holdings) at $520.00, reducing his position from 8,771 to 6,371 shares. The sale occurred near the top of ISRG's 52-week range ($370.62–$610.45), roughly 15.3% below the 52-week high. Across his cross-ticker trading history, NACHTSHEIM shows a 100% win rate on his prior buys over 90 days (average return +21.8%), suggesting general discipline in entry timing; however, this sell represents a discrete liquidity or portfolio decision rather than a broader conviction signal. The company itself remains operationally strong—recording $2.3B in quarterly revenue with 17.2% annual growth and a $698.4M quarterly net income—though the elevated P/E of 74.85 reflects high valuation expectations embedded in the stock's current $185.4B market cap.
