Jiangsu Zhengdan Chemical Industry Co., Ltd. (SZSE:300641) shareholders are no doubt pleased to see that the share price has bounced 28% in the last month, although it is still struggling to make up recently lost ground. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 21% over that time.

Even after such a large jump in price, Jiangsu Zhengdan Chemical Industry's price-to-sales (or "P/S") ratio of 1.4x 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. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

What Does Jiangsu Zhengdan Chemical Industry's Recent Performance Look Like?

As an illustration, revenue has deteriorated at Jiangsu Zhengdan Chemical Industry over the last year, which is not ideal at all. Perhaps the market believes the recent revenue performance isn't good enough to keep up the industry, causing the P/S ratio to suffer. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

How Is Jiangsu Zhengdan Chemical Industry's Revenue Growth Trending?

Jiangsu Zhengdan Chemical Industry's P/S ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the industry.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 25%. Regardless, revenue has managed to lift by a handy 17% in aggregate from three years ago, thanks to the earlier period of growth. Although it's been a bumpy ride, it's still fair to say the revenue growth recently has been mostly respectable for the company.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 25% shows it's noticeably less attractive.

In light of this, it's understandable that Jiangsu Zhengdan Chemical Industry'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 Final Word

Despite Jiangsu Zhengdan Chemical Industry's share price climbing recently, its P/S still lags most other companies. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Jiangsu Zhengdan Chemical Industry 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. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises. If recent medium-term revenue trends continue, it's hard to see the share price experience a reversal of fortunes anytime soon.
