China Leon Inspection Holding Limited (HKG:1586) shares have had a really impressive month, gaining 38% after a shaky period beforehand. Looking back a bit further, it's encouraging to see the stock is up 40% in the last year.

Following the firm bounce in price, China Leon Inspection Holding's price-to-earnings (or "P/E") ratio of 13x might make it look like a sell right now compared to the market in Hong Kong, where around half of the companies have P/E ratios below 9x and even P/E's below 5x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

We'd have to say that with no tangible growth over the last year, China Leon Inspection Holding's earnings have been unimpressive. It might be that many are expecting an improvement to the uninspiring earnings performance over the coming period, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For China Leon Inspection Holding?

China Leon Inspection 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, the company posted a result that saw barely any deviation from a year ago. Although pleasingly EPS has lifted 35% in aggregate from three years ago, notwithstanding the last 12 months. So we can start by confirming that the company has done a great job of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 22% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

In light of this, it's alarming that China Leon Inspection Holding's P/E sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. 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 Key Takeaway

The large bounce in China Leon Inspection Holding's shares has lifted the company's P/E to a fairly high level. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

Our examination of China Leon Inspection Holding 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.
