China Boton Group Company Limited (HKG:3318) shares have continued their recent momentum with a 41% gain in the last month alone. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 16% over that time.

Following the firm bounce in price, China Boton Group may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 16.7x, since almost half of all companies in Hong Kong have P/E ratios under 9x and even P/E's lower than 5x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

With earnings growth that's exceedingly strong of late, China Boton Group has been doing very well. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is China Boton Group's Growth Trending?

China Boton Group's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 203% last year. The latest three year period has also seen a 15% overall rise in EPS, aided extensively by its short-term performance. Accordingly, shareholders would have probably been satisfied with the medium-term rates of earnings growth.

This is in contrast to the rest of the market, which is expected to grow by 20% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that China Boton Group's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Final Word

China Boton Group's P/E is flying high just like its stock has during the last month. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of China Boton Group revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
