With a price-to-earnings (or "P/E") ratio of 5.8x China Communications Services Corporation Limited (HKG:552) 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. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

Recent times have been pleasing for China Communications Services as its earnings have risen in spite of the market's earnings going into reverse. 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.

Does Growth Match The Low P/E?

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

Taking a look back first, we see that the company managed to grow earnings per share by a handy 7.9% last year. EPS has also lifted 20% in aggregate from three years ago, partly thanks to the last 12 months of growth. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Shifting to the future, estimates from the eight analysts covering the company suggest earnings should grow by 11% per annum over the next three years. Meanwhile, the rest of the market is forecast to expand by 16% per annum, which is noticeably more attractive.

With this information, we can see why China Communications Services is trading at a P/E lower than the market. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Key Takeaway

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.

As we suspected, our examination of China Communications Services' analyst forecasts revealed that its inferior earnings outlook 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. It's hard to see the share price rising strongly in the near future under these circumstances.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with China Communications Services, and understanding should be part of your investment process.
