Zhong An Group Limited (HKG:672) shares have continued their recent momentum with a 26% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 26%.

In spite of the firm bounce in price, Zhong An Group may still be sending very bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 2.1x, since almost half of all companies in Hong Kong have P/E ratios greater than 10x and even P/E's higher than 20x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

With earnings growth that's exceedingly strong of late, Zhong An Group has been doing very well. One possibility is that the P/E is low because investors think this strong earnings growth might actually underperform the broader market in the near future. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

How Is Zhong An Group's Growth Trending?

In order to justify its P/E ratio, Zhong An Group would need to produce anemic growth that's substantially trailing the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 41% last year. Still, incredibly EPS has fallen 35% in total from three years ago, which is quite disappointing. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 22% shows it's an unpleasant look.

With this information, we are not surprised that Zhong An Group is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Bottom Line On Zhong An Group's P/E

Even after such a strong price move, Zhong An Group's P/E still trails the rest of the market significantly. 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.

We've established that Zhong An Group maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
