The Kimou Environmental Holding Limited (HKG:6805) share price has done very well over the last month, posting an excellent gain of 28%. The last 30 days bring the annual gain to a very sharp 29%.

Following the firm bounce in price, Kimou Environmental Holding may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 13.8x, 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. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

As an illustration, earnings have deteriorated at Kimou Environmental Holding over the last year, which is not ideal at all. One possibility is that the P/E is high because investors think the company will still do 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.

What Are Growth Metrics Telling Us About The High P/E?

Kimou Environmental Holding's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 18%. The last three years don't look nice either as the company has shrunk EPS by 10% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

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 find it concerning that Kimou Environmental Holding is trading at a P/E higher than the market. 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. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Final Word

The large bounce in Kimou Environmental Holding's shares has lifted the company's P/E to a fairly high level. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that Kimou Environmental Holding currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely 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.
