China Qinfa Group Limited (HKG:866) shareholders have had their patience rewarded with a 38% share price jump in the last month. This latest share price bounce rounds out a remarkable 369% gain over the last twelve months.

Since its price has surged higher, China Qinfa Group's price-to-earnings (or "P/E") ratio of 22.2x might make it look like a strong sell right now compared to the market in Hong Kong, where around half of the companies have P/E ratios below 8x 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 highly elevated P/E.

As an illustration, earnings have deteriorated at China Qinfa Group over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies 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.

How Is China Qinfa Group's Growth Trending?

In order to justify its P/E ratio, China Qinfa Group would need to produce outstanding growth well in excess of the market.

Retrospectively, the last year delivered a frustrating 58% decrease to the company's bottom line. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 22% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that China Qinfa Group is trading at a P/E higher than the market. 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 Final Word

Shares in China Qinfa Group have built up some good momentum lately, which has really inflated its P/E. 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 China Qinfa Group currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. 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.
