With a median price-to-sales (or "P/S") ratio of close to 3.5x in the Pharmaceuticals industry in China, you could be forgiven for feeling indifferent about Hainan Haiyao Co., Ltd.'s (SZSE:000566) P/S ratio, which comes in at about the same. 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 Hainan Haiyao's P/S Mean For Shareholders?

For instance, Hainan Haiyao's receding revenue in recent times would have to be some food for thought. Perhaps investors believe the recent revenue performance is enough to keep in line with the industry, which is keeping the P/S from dropping off. If not, then existing shareholders may be a little nervous about the viability of the share price.

Is There Some Revenue Growth Forecasted For Hainan Haiyao?

Hainan Haiyao'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.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 23%. As a result, revenue from three years ago have also fallen 28% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Comparing that to the industry, which is predicted to deliver 36% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

With this in mind, we find it worrying that Hainan Haiyao's P/S exceeds that of its industry peers. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh on the share price eventually.

The Key Takeaway

Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our look at Hainan Haiyao revealed its shrinking revenues over the medium-term haven't impacted the P/S as much as we anticipated, given the industry is set to grow. Even though it matches the industry, we're uncomfortable with the current P/S ratio, as this dismal revenue performance is unlikely to support a more positive sentiment for long. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.
