Wintime Energy Group Co.,Ltd.'s (SHSE:600157) price-to-earnings (or "P/E") ratio of 12.6x might 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 32x and even P/E's above 60x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.

With earnings growth that's superior to most other companies of late, Wintime Energy GroupLtd has been doing relatively well. 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.

How Is Wintime Energy GroupLtd's Growth Trending?

There's an inherent assumption that a company should far underperform the market for P/E ratios like Wintime Energy GroupLtd's to be considered reasonable.

Taking a look back first, we see that the company grew earnings per share by an impressive 16% last year. Still, incredibly EPS has fallen 50% in total from three years ago, which is quite disappointing. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 10% each year as estimated by the three analysts watching the company. With the market predicted to deliver 26% growth each year, the company is positioned for a weaker earnings result.

In light of this, it's understandable that Wintime Energy GroupLtd's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.
