Although ISRG is somewhat exposed to broad market movements, its beta is moderate, indicating the stock moves in line with the market but maintains some defensive characteristics due to its healthcare focus.

The stock experiences moderate volatility relative to its healthcare peers, reflecting both growth expectations and sector-specific risks.
