The Hebei Construction Group Corporation Limited (HKG:1727) share price has done very well over the last month, posting an excellent gain of 37%. Longer-term shareholders would be thankful for the recovery in the share price since it's now virtually flat for the year after the recent bounce.

In spite of the firm bounce in price, Hebei Construction Group may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 6.2x, 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. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

For example, consider that Hebei Construction Group's financial performance has been poor lately as its earnings have been in decline. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

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

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 36%. This means it has also seen a slide in earnings over the longer-term as EPS is down 76% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 22% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's understandable that Hebei Construction Group's P/E would sit below the majority of other companies. However, we think shrinking earnings are unlikely to lead to a stable P/E over the longer term, which could set up shareholders for future disappointment. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Final Word

Hebei Construction Group's stock might have been given a solid boost, but its P/E certainly hasn't reached any great heights. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Hebei Construction 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.
