With a median price-to-sales (or "P/S") ratio of close to 6.1x in the Software industry in China, you could be forgiven for feeling indifferent about Sinodata Co., Ltd.'s (SZSE:002657) P/S ratio of 5.2x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

What Does Sinodata's Recent Performance Look Like?

As an illustration, revenue has deteriorated at Sinodata over the last year, which is not ideal at all. One possibility is that the P/S is moderate because investors think the company might still do enough to be in line with the broader industry in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

Sinodata'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 a frustrating 18% decrease to the company's top line. This means it has also seen a slide in revenue over the longer-term as revenue is down 23% in total over the last three years. 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 information, we find it concerning that Sinodata is trading at a fairly similar P/S compared to the industry. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. 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

While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

Our look at Sinodata 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. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
