It's not a stretch to say that Towngas Smart Energy Company Limited's (HKG:1083) price-to-earnings (or "P/E") ratio of 9.1x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 10x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

Towngas Smart Energy 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 not, then existing shareholders have reason to be feeling optimistic about the future direction of the share price.

What Are Growth Metrics Telling Us About The P/E?

There's an inherent assumption that a company should be matching the market for P/E ratios like Towngas Smart Energy's to be considered reasonable.

Retrospectively, the last year delivered a decent 12% gain to the company's bottom line. Still, lamentably EPS has fallen 38% in aggregate from three years ago, which is disappointing. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 14% each year during the coming three years according to the eleven analysts following the company. That's shaping up to be materially higher than the 12% per annum growth forecast for the broader market.

In light of this, it's curious that Towngas Smart Energy's P/E sits in line with the majority of other companies. Apparently some shareholders are skeptical of the forecasts and have been accepting lower selling prices.
