Gansu Yatai Industrial Developent Co.,Ltd. (SZSE:000691) shareholders have had their patience rewarded with a 26% share price jump in the last month. Longer-term shareholders would be thankful for the recovery in the share price since it's now virtually flat for the year after the recent bounce.

Since its price has surged higher, you could be forgiven for thinking Gansu Yatai Industrial DevelopentLtd is a stock not worth researching with a price-to-sales ratios (or "P/S") of 3.7x, considering almost half the companies in China's Chemicals industry have P/S ratios below 1.9x. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's as high as it is.

How Has Gansu Yatai Industrial DevelopentLtd Performed Recently?

As an illustration, revenue has deteriorated at Gansu Yatai Industrial DevelopentLtd over the last year, which is not ideal at all. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. If not, then existing shareholders may be quite nervous about the viability of the share price.

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

The only time you'd be truly comfortable seeing a P/S as high as Gansu Yatai Industrial DevelopentLtd's is when the company's growth is on track to outshine the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 26%. The last three years don't look nice either as the company has shrunk revenue by 16% in aggregate. 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 23% 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 Gansu Yatai Industrial DevelopentLtd's P/S exceeds that of its industry peers. 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 heavily on the share price eventually.

The Key Takeaway

Gansu Yatai Industrial DevelopentLtd shares have taken a big step in a northerly direction, but its P/S is elevated as a result. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Gansu Yatai Industrial DevelopentLtd revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
