Zhejiang Tuna Environmental Science & TechnologyCo.,Ltd.'s (SHSE:603177) price-to-sales (or "P/S") ratio of 1.8x might make it look like a buy right now compared to the Commercial Services industry in China, where around half of the companies have P/S ratios above 2.4x and even P/S above 5x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

What Does Zhejiang Tuna Environmental Science & TechnologyCo.Ltd's Recent Performance Look Like?

We'd have to say that with no tangible growth over the last year, Zhejiang Tuna Environmental Science & TechnologyCo.Ltd's revenue has been unimpressive. Perhaps the market believes the recent lacklustre revenue performance is a sign of future underperformance relative to industry peers, hurting the P/S. 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 out of favour.

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

The only time you'd be truly comfortable seeing a P/S as low as Zhejiang Tuna Environmental Science & TechnologyCo.Ltd's is when the company's growth is on track to lag the industry.

Taking a look back first, we see that there was hardly any revenue growth to speak of for the company over the past year. Still, the latest three year period has seen an excellent 71% overall rise in revenue, in spite of its uninspiring short-term performance. Accordingly, shareholders will be pleased, but also have some questions to ponder about the last 12 months.

This is in contrast to the rest of the industry, which is expected to grow by 30% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this in consideration, it's easy to understand why Zhejiang Tuna Environmental Science & TechnologyCo.Ltd's P/S falls short of the mark set by its industry peers. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Final Word

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 examination of Zhejiang Tuna Environmental Science & TechnologyCo.Ltd confirms that the company's revenue trends over the past three-year years are a key factor in its low price-to-sales ratio, as we suspected, given they fall short of current industry expectations. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. If recent medium-term revenue trends continue, it's hard to see the share price experience a reversal of fortunes anytime soon.
