The Transocean Ltd. (NYSE:RIG) share price has done very well over the last month, posting an excellent gain of 28%. The last 30 days bring the annual gain to a very sharp 41%.

Although its price has surged higher, it's still not a stretch to say that Transocean's price-to-sales (or "P/S") ratio of 1.5x right now seems quite "middle-of-the-road" compared to the Energy Services industry in the United States, where the median P/S ratio is around 1.2x. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

What Does Transocean's Recent Performance Look Like?

Transocean certainly has been doing a good job lately as it's been growing revenue more than most other companies. It might be that many expect the strong revenue performance to wane, which has kept the P/S ratio from rising. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

What Are Revenue Growth Metrics Telling Us About The P/S?

Transocean's P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry.

Retrospectively, the last year delivered an exceptional 17% gain to the company's top line. The strong recent performance means it was also able to grow revenue by 50% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been superb for the company.

Turning to the outlook, the next year should generate growth of 0.2% as estimated by the eight analysts watching the company. Meanwhile, the rest of the industry is forecast to expand by 2.3%, which is noticeably more attractive.

In light of this, it's curious that Transocean's P/S sits in line with the majority of other companies. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for future disappointment if the P/S falls to levels more in line with the growth outlook.

What Does Transocean's P/S Mean For Investors?

Its shares have lifted substantially and now Transocean's P/S is back within range of the industry median. 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.

When you consider that Transocean's revenue growth estimates are fairly muted compared to the broader industry, it's easy to see why we consider it unexpected to be trading at its current P/S ratio. At present, we aren't confident in the P/S as the predicted future revenues aren't likely to support a more positive sentiment for long. A positive change is needed in order to justify the current price-to-sales ratio.

Of course, profitable companies with a history of great earnings growth are generally safer bets. So you may wish to see this free collection of other companies that have reasonable P/E ratios and have grown earnings strongly.
