Hengxin Technology Ltd. (HKG:1085) shareholders would be excited to see that the share price has had a great month, posting a 28% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 28% in the last twelve months.

In spite of the firm bounce in price, you could still be forgiven for feeling indifferent about Hengxin Technology's P/E ratio of 9.6x, since the median price-to-earnings (or "P/E") ratio in Hong Kong is also close to 10x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

Earnings have risen firmly for Hengxin Technology recently, which is pleasing to see. It might be that many expect the respectable earnings performance to wane, which has kept the P/E from rising. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

Does Growth Match The P/E?

In order to justify its P/E ratio, Hengxin Technology would need to produce growth that's similar to the market.

Taking a look back first, we see that the company managed to grow earnings per share by a handy 9.6% last year. However, this wasn't enough as the latest three year period has seen an unpleasant 5.2% overall 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 21% 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 find it concerning that Hengxin Technology is trading at a fairly similar P/E to the market. It seems most investors are ignoring the recent poor growth rate 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 on the share price eventually.

The Final Word

Its shares have lifted substantially and now Hengxin Technology's P/E is also back up to the market median. 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 Hengxin Technology currently trades on a higher than expected P/E since its recent earnings have been in decline over the medium-term. Right now we are uncomfortable with the P/E as this earnings performance is unlikely to support a more positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
