Shuangliang Eco-Energy Systems Co.,Ltd (SHSE:600481) shareholders are no doubt pleased to see that the share price has bounced 29% 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 35% over that time.

In spite of the firm bounce in price, Shuangliang Eco-Energy SystemsLtd's price-to-earnings (or "P/E") ratio of 10.3x might still make it look like a strong buy right now compared to the market in China, where around half of the companies have P/E ratios above 31x and even P/E's above 56x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Shuangliang Eco-Energy SystemsLtd has been doing quite well of late. It might be that many expect the strong earnings performance to degrade substantially, possibly more than the market, which has repressed the P/E. 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.

Keen to find out how analysts think Shuangliang Eco-Energy SystemsLtd's future stacks up against the industry? In that case, our free report is a great place to start.

Does Growth Match The Low P/E?

Shuangliang Eco-Energy SystemsLtd's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 48% last year. The latest three year period has also seen an excellent 907% overall rise in EPS, aided by its short-term performance. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 53% during the coming year according to the four analysts following the company. Meanwhile, the rest of the market is forecast to only expand by 41%, which is noticeably less attractive.

With this information, we find it odd that Shuangliang Eco-Energy SystemsLtd is trading at a P/E lower than the market. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

The Final Word

Shares in Shuangliang Eco-Energy SystemsLtd are going to need a lot more upward momentum to get the company's P/E out of its slump. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Shuangliang Eco-Energy SystemsLtd's analyst forecasts revealed that its superior earnings outlook isn't contributing to its P/E anywhere near as much as we would have predicted. There could be some major unobserved threats to earnings preventing the P/E ratio from matching the positive outlook. At least price risks look to be very low, but investors seem to think future earnings could see a lot of volatility.

And what about other risks? Every company has them, and we've spotted 3 warning signs for Shuangliang Eco-Energy SystemsLtd (of which 1 shouldn't be ignored!) you should know about.
