How to Interpret $ISRG Trades
Not every insider transaction in INTUITIVE SURGICAL INC is a signal for immediate action. Professional investors look for "cluster buying"—when multiple executives simultaneously purchase $ISRG shares on the open market. It is crucial to distinguish between scheduled sales (under Rule 10b5-1) and voluntary increases in ownership, which demonstrate management’s true conviction that the stock is undervalued.

Insider activity data for INTUITIVE SURGICAL INC is streamed in real-time directly from the SEC EDGAR system.

TRADE DATE: The actual day the insider executed the purchase or sale in the market.
