Zhongman Petroleum and Natural Gas Group Corp.,Ltd.'s (SHSE:603619) price-to-earnings (or "P/E") ratio of 12x 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 34x and even P/E's above 67x 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, Zhongman Petroleum and Natural Gas GroupLtd has been doing quite well of late. One possibility is that the P/E is low because investors think the company's earnings are going to fall away like everyone else's soon. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

How Is Zhongman Petroleum and Natural Gas GroupLtd's Growth Trending?

In order to justify its P/E ratio, Zhongman Petroleum and Natural Gas GroupLtd would need to produce anemic growth that's substantially trailing the market.

Taking a look back first, we see that there was hardly any earnings per share growth to speak of for the company over the past year. Likewise, not much has changed from three years ago as earnings have been stuck during that whole time. Therefore, it's fair to say that earnings growth has definitely eluded the company recently.

Shifting to the future, estimates from the three analysts covering the company suggest earnings should grow by 41% over the next year. That's shaping up to be similar to the 41% growth forecast for the broader market.

With this information, we find it odd that Zhongman Petroleum and Natural Gas GroupLtd is trading at a P/E lower than the market. It may be that most investors are not convinced the company can achieve future growth expectations.

The Key Takeaway

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Zhongman Petroleum and Natural Gas GroupLtd currently trades on a lower than expected P/E since its forecast growth is in line with the wider market. When we see an average earnings outlook with market-like growth, we assume potential risks are what might be placing pressure on the P/E ratio. It appears some are indeed anticipating earnings instability, because these conditions should normally provide more support to the share price.
