Those holding Anhui Tongyuan Environment Energy Saving Co.,Ltd (SHSE:688679) shares would be relieved that the share price has rebounded 27% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 19% in the last twelve months.

After such a large jump in price, Anhui Tongyuan Environment Energy SavingLtd's price-to-earnings (or "P/E") ratio of 41x might make it look like a sell right now compared to the market in China, where around half of the companies have P/E ratios below 31x and even P/E's below 19x 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 as high as it is.

As an illustration, earnings have deteriorated at Anhui Tongyuan Environment Energy SavingLtd over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

Is There Enough Growth For Anhui Tongyuan Environment Energy SavingLtd?

Anhui Tongyuan Environment Energy SavingLtd's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 31%. As a result, earnings from three years ago have also fallen 74% overall. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 40% shows it's an unpleasant look.

In light of this, it's alarming that Anhui Tongyuan Environment Energy SavingLtd's P/E sits above the majority of other companies. 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 earnings trends is likely to weigh heavily on the share price eventually.

What We Can Learn From Anhui Tongyuan Environment Energy SavingLtd's P/E?
