Intuitive Surgical stock (NASDAQ: ISRG) has dropped 16% this year, notably lagging behind the S&P 500’s 10% increase. The stock has experienced downward pressure recently after management indicated that potential tariffs may adversely affect its performance in 2026.
This raises an essential question: Is ISRG a buy at below $450? We believe it is. Although the stock’s high valuation makes it susceptible to negative events, we perceive little cause for concern regarding the company’s fundamental operations. Our assessment is grounded in an examination of Intuitive Surgical’s critical metrics—such as Growth, Profitability, and Financial Stability—which indicate that its operational performance and financial state continue to be exceptionally robust.
However, if you are looking for an upside with reduced volatility compared to holding an individual stock, consider the High Quality Portfolio. It has consistently outperformed its benchmark—a mix of the S&P 500, Russell, and S&P MidCap indexes—and has realized returns surpassing 91% since its inception.

Putting All The Pieces Together: What It Means For ISRG Stock
In conclusion, Intuitive Surgical’s performance across the parameters outlined above is as follows:
• Growth: Very Strong
• Profitability: Very Strong
• Financial Stability: Very Strong
• Downturn Resilience: Moderate
• Overall: Very Strong
Although Intuitive Surgical’s valuation is undeniably high, it’s crucial to recognize that the stock has historically commanded a premium. For context, its average price-to-sales ratio over the last five years is 19.5, with an average P/E ratio of 75.
In our opinion, this premium is warranted due to several factors: improving revenue growth and margins, a near-monopoly status in the robotic surgery sector, and a significant base of recurring revenue. For these reasons, we believe ISRG is an attractive stock to purchase at its present levels.
The primary risk is that concerns over tariffs in 2026 could discourage investors from paying an even higher multiple in the short term. However, for those with a 3-to-5-year investment outlook, we believe that the company’s solid fundamentals present a compelling opportunity.
