It's not a stretch to say that China Resources Gas Group Limited's (HKG:1193) price-to-earnings (or "P/E") ratio of 10.9x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 9x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

China Resources Gas 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 wane, which has kept the P/E from rising. 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 not quite in favour.

Does Growth Match The P/E?

The only time you'd be comfortable seeing a P/E like China Resources Gas Group's is when the company's growth is tracking the market closely.

Taking a look back first, we see that the company managed to grow earnings per share by a handy 10% last year. Ultimately though, it couldn't turn around the poor performance of the prior period, with EPS shrinking 2.2% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 8.4% each year over the next three years. Meanwhile, the rest of the market is forecast to expand by 15% per annum, which is noticeably more attractive.

With this information, we find it interesting that China Resources Gas Group is trading at a fairly similar P/E to the market. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. Maintaining these prices will be difficult to achieve as this level of earnings growth is likely to weigh down the shares eventually.

The Final Word

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of China Resources Gas Group's analyst forecasts revealed that its inferior earnings outlook isn't impacting its P/E as much as we would have predicted. Right now we are uncomfortable with the P/E as the predicted future earnings aren't likely to support a more positive sentiment for long. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
