Poly Union Chemical Holding Group Co., Ltd. (SZSE:002037) shareholders would be excited to see that the share price has had a great month, posting a 27% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 19% in the last twelve months.

Even after such a large jump in price, Poly Union Chemical Holding Group's price-to-sales (or "P/S") ratio of 0.5x might still make it look like a buy right now compared to the Chemicals industry in China, where around half of the companies have P/S ratios above 2.1x and even P/S above 5x are quite common. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

How Poly Union Chemical Holding Group Has Been Performing

We'd have to say that with no tangible growth over the last year, Poly Union Chemical Holding Group's revenue has been unimpressive. It might be that many expect the uninspiring revenue performance to worsen, which has repressed 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?

In order to justify its P/S ratio, Poly Union Chemical Holding Group would need to produce sluggish growth that's trailing the industry.

Retrospectively, the last year delivered virtually the same number to the company's top line as the year before. Likewise, not much has changed from three years ago as revenue have been stuck during that whole time. So it seems apparent to us that the company has struggled to grow revenue meaningfully over that time.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 23% shows it's noticeably less attractive.

In light of this, it's understandable that Poly Union Chemical Holding Group's P/S sits below the majority of other companies. 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 Key Takeaway

The latest share price surge wasn't enough to lift Poly Union Chemical Holding Group's P/S close to the industry median. 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.

As we suspected, our examination of Poly Union Chemical Holding Group revealed its three-year revenue trends are contributing to its low P/S, given they look worse than 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. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
