You may think that with a price-to-sales (or "P/S") ratio of 23.7x Intuitive Surgical, Inc. (NASDAQ:ISRG) is a stock to avoid completely, seeing as almost half of all the Medical Equipment companies in the United States have P/S ratios under 3.3x and even P/S lower than 1.2x aren't out of the ordinary. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does Intuitive Surgical's P/S Mean For Shareholders?

Recent times have been advantageous for Intuitive Surgical as its revenues have been rising faster than most other companies. The P/S is probably high because investors think this strong revenue performance will continue. If not, then existing shareholders might be a little nervous about the viability of the share price.

How Is Intuitive Surgical's Revenue Growth Trending?

In order to justify its P/S ratio, Intuitive Surgical would need to produce outstanding growth that's well in excess of the industry.

Taking a look back first, we see that the company managed to grow revenues by a handy 15% last year. The latest three year period has also seen an excellent 43% overall rise in revenue, aided somewhat by its short-term performance. So we can start by confirming that the company has done a great job of growing revenues over that time.

Turning to the outlook, the next three years should generate growth of 15% per annum as estimated by the analysts watching the company. With the industry only predicted to deliver 9.3% each year, the company is positioned for a stronger revenue result.

With this information, we can see why Intuitive Surgical is trading at such a high P/S compared to the industry. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

What Does Intuitive Surgical's P/S Mean For Investors?

It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Intuitive Surgical maintains its high P/S on the strength of its forecasted revenue growth being higher than the the rest of the Medical Equipment industry, as expected. At this stage investors feel the potential for a deterioration in revenues is quite remote, justifying the elevated P/S ratio. It's hard to see the share price falling strongly in the near future under these circumstances.
