With a price-to-earnings (or "P/E") ratio of 5.9x Yankuang Energy Group Company Limited (HKG:1171) may be sending bullish signals at the moment, given that almost half of all companies in Hong Kong have P/E ratios greater than 10x and even P/E's higher than 19x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Yankuang Energy Group hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It seems that many are expecting the dour earnings performance to persist, which has repressed the P/E. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

How Is Yankuang Energy Group's Growth Trending?

Yankuang Energy Group's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 58%. Still, the latest three year period has seen an excellent 30% overall rise in EPS, in spite of its unsatisfying short-term performance. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Turning to the outlook, the next year should bring diminished returns, with earnings decreasing 19% as estimated by the four analysts watching the company. With the market predicted to deliver 23% growth , that's a disappointing outcome.

With this information, we are not surprised that Yankuang Energy Group is trading at a P/E lower than the market. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

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.

As we suspected, our examination of Yankuang Energy Group's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
