Despite an already strong run, Computime Group Limited (HKG:320) shares have been powering on, with a gain of 26% in the last thirty days. The last 30 days bring the annual gain to a very sharp 28%.

Even after such a large jump in price, Computime Group's price-to-earnings (or "P/E") ratio of 5.1x might still make it look like a buy right now compared to the market in Hong Kong, where around half of the companies have P/E ratios above 10x and even P/E's above 19x are quite common. 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 quite advantageous for Computime Group as its earnings have been rising very briskly. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

In order to justify its P/E ratio, Computime Group would need to produce sluggish growth that's trailing the market.

Retrospectively, the last year delivered an exceptional 278% gain to the company's bottom line. Still, EPS has barely risen at all from three years ago in total, which is not ideal. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 21% shows it's noticeably less attractive on an annualised basis.

In light of this, it's understandable that Computime Group's P/E sits below the majority of other companies. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Final Word

The latest share price surge wasn't enough to lift Computime Group's P/E close to the market median. 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.

As we suspected, our examination of Computime Group revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. If recent medium-term earnings trends continue, it's hard to see the share price rising strongly in the near future under these circumstances.
