Wetown Electric Group Co., Ltd. (SHSE:688226) shares have retraced a considerable 28% in the last month, reversing a fair amount of their solid recent performance. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 26% in that time.

Since its price has dipped substantially, Wetown Electric Group's price-to-earnings (or "P/E") ratio of 18.4x might make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 30x and even P/E's above 55x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

Wetown Electric Group certainly has been doing a good job lately as it's been growing earnings more than most other companies. It might be that many expect the strong earnings performance to degrade substantially, 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.

What Are Growth Metrics Telling Us About The Low P/E?

There's an inherent assumption that a company should underperform the market for P/E ratios like Wetown Electric Group's to be considered reasonable.

If we review the last year of earnings growth, the company posted a terrific increase of 105%. Pleasingly, EPS has also lifted 81% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 38% per year as estimated by the one analyst watching the company. With the market only predicted to deliver 25% per year, the company is positioned for a stronger earnings result.

With this information, we find it odd that Wetown Electric Group is trading at a P/E lower than the market. It looks like most investors are not convinced at all that the company can achieve future growth expectations.

The Bottom Line On Wetown Electric Group's P/E

The softening of Wetown Electric Group's shares means its P/E is now sitting at a pretty low level. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

Our examination of Wetown Electric Group'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. It appears many are indeed anticipating earnings instability, because these conditions should normally provide a boost to the share price.
