The Hygieia Group Limited (HKG:1650) share price has done very well over the last month, posting an excellent gain of 29%. Taking a wider view, although not as strong as the last month, the full year gain of 21% is also fairly reasonable.

In spite of the firm bounce in price, there still wouldn't be many who think Hygieia Group's price-to-sales (or "P/S") ratio of 0.5x is worth a mention when the median P/S in Hong Kong's Commercial Services industry is similar at about 0.4x. 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.

How Has Hygieia Group Performed Recently?

For instance, Hygieia Group's receding revenue in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing revenue performance behind them over the coming period, which has kept the P/S from falling. If you like the company, you'd at least be hoping this is 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?

Hygieia Group'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 15% decrease to the company's top line. As a result, revenue from three years ago have also fallen 20% overall. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Comparing that to the industry, which is predicted to deliver 6.4% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's somewhat alarming that Hygieia Group's P/S sits in line with the majority of other companies. 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 Final Word

Hygieia Group appears to be back in favour with a solid price jump bringing its P/S back in line with other companies in the industry 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.

The fact that Hygieia Group currently trades at a P/S on par with the rest of the industry is surprising to us since its recent revenues have been in decline over the medium-term, all while 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. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
