Those holding China Conch Environment Protection Holdings Limited (HKG:587) shares would be relieved that the share price has rebounded 28% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. But the last month did very little to improve the 61% share price decline over the last year.

Although its price has surged higher, China Conch Environment Protection Holdings' price-to-earnings (or "P/E") ratio of 6.2x 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 20x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

As an illustration, earnings have deteriorated at China Conch Environment Protection Holdings over the last year, which is not ideal at all. One possibility is that the P/E is low because investors think the company won't do enough to avoid underperforming the broader market in the near future. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Is There Any Growth For China Conch Environment Protection Holdings?

The only time you'd be truly comfortable seeing a P/E as low as China Conch Environment Protection Holdings' is when the company's growth is on track to lag the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 20%. The last three years don't look nice either as the company has shrunk EPS by 44% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 21% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we are not surprised that China Conch Environment Protection Holdings is trading at a P/E lower than the market. 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. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

The Final Word

China Conch Environment Protection Holdings' stock might have been given a solid boost, but its P/E certainly hasn't reached any great heights. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that China Conch Environment Protection Holdings maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
