Wetown Electric Group Co., Ltd.'s (SHSE:688226) 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 34x and even P/E's above 64x 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 limited.

Wetown Electric Group certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. 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 not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Does Growth Match 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.

Taking a look back first, we see that the company grew earnings per share by an impressive 107% last year. Pleasingly, EPS has also lifted 72% 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.

Looking ahead now, EPS is anticipated to climb by 32% per annum during the coming three years according to the dual analysts following the company. That's shaping up to be materially higher than the 19% per annum growth forecast for the broader market.

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 Final Word

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Wetown Electric Group currently trades on a much lower than expected P/E since its forecast growth is higher than the wider market. When we see a strong earnings outlook with faster-than-market growth, we assume potential risks are what might be placing significant pressure on the P/E ratio. At least price risks look to be very low, but investors seem to think future earnings could see a lot of volatility.
