There wouldn't be many who think China Communications Services Corporation Limited's (HKG:552) price-to-earnings (or "P/E") ratio of 7.8x is worth a mention when the median P/E in Hong Kong is similar at about 9x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

With earnings growth that's superior to most other companies of late, China Communications Services has been doing relatively well. It might be that many expect the strong earnings performance to wane, which has kept the P/E from rising. If not, then existing shareholders have reason to be feeling optimistic about the future direction of the share price.

Does Growth Match The P/E?

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

If we review the last year of earnings growth, the company posted a worthy increase of 6.7%. The latest three year period has also seen a 16% overall rise in EPS, aided somewhat by its short-term performance. Accordingly, shareholders would have probably been satisfied with the medium-term rates of earnings growth.

Turning to the outlook, the next three years should generate growth of 7.0% each year as estimated by the seven analysts watching the company. With the market predicted to deliver 16% growth each year, the company is positioned for a weaker earnings result.

In light of this, it's curious that China Communications Services' P/E sits in line with the majority of other companies. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. These shareholders may be setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

What We Can Learn From China Communications Services' P/E?

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 China Communications Services currently trades on a higher than expected P/E since its forecast growth is lower than the wider market. 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. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
