Unfortunately for some shareholders, the Xinya Electronic Co., Ltd. (SHSE:605277) share price has dived 26% in the last thirty days, prolonging recent pain. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 15% share price drop.

Since its price has dipped substantially, Xinya Electronic's price-to-earnings (or "P/E") ratio of 20.4x might make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 27x and even P/E's above 48x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

For example, consider that Xinya Electronic's financial performance has been poor lately as its earnings have been in decline. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

In order to justify its P/E ratio, Xinya Electronic would need to produce sluggish growth that's trailing the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 11%. The last three years don't look nice either as the company has shrunk EPS by 15% in aggregate. 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 41% 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 Xinya Electronic is trading at a P/E lower than the market. However, we think shrinking earnings are unlikely to lead to a stable P/E over the longer term, which could set up shareholders for future disappointment. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Bottom Line On Xinya Electronic's P/E

Xinya Electronic's recently weak share price has pulled its P/E below most other companies. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

As we suspected, our examination of Xinya Electronic revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
