Despite an already strong run, Changhong Jiahua Holdings Limited (HKG:3991) shares have been powering on, with a gain of 40% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 36% in the last year.

Even after such a large jump in price, given about half the companies in Hong Kong have price-to-earnings ratios (or "P/E's") above 10x, you may still consider Changhong Jiahua Holdings as a highly attractive investment with its 4.7x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.

We'd have to say that with no tangible growth over the last year, Changhong Jiahua Holdings' earnings have been unimpressive. One possibility is that the P/E is low because investors think this benign earnings growth rate will likely underperform the broader market in the near future. If not, then existing shareholders may be feeling optimistic about the future direction of the share price.

Is There Any Growth For Changhong Jiahua Holdings?

In order to justify its P/E ratio, Changhong Jiahua Holdings would need to produce anemic growth that's substantially trailing the market.

Retrospectively, the last year delivered virtually the same number to the company's bottom line as the year before. The lack of growth did nothing to help the company's aggregate three-year performance, which is an unsavory 5.5% drop in EPS. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Comparing that to the market, which is predicted to deliver 23% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we are not surprised that Changhong Jiahua Holdings is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

What We Can Learn From Changhong Jiahua Holdings' P/E?

Changhong Jiahua Holdings' recent share price jump still sees its P/E sitting firmly flat on the ground. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Changhong Jiahua Holdings 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. If recent medium-term earnings trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.
