Qingdao Foods Co., Ltd.'s (SZSE:001219) price-to-earnings (or "P/E") ratio of 29.3x 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 36x and even P/E's above 70x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

Qingdao Foods has been doing a good job lately as it's been growing earnings at a solid pace. It might be that many expect the respectable earnings performance to degrade substantially, which has repressed the P/E. If that doesn't eventuate, then existing shareholders have reason to be optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

The only time you'd be truly comfortable seeing a P/E as low as Qingdao Foods' is when the company's growth is on track to lag the market.

Taking a look back first, we see that the company managed to grow earnings per share by a handy 8.8% last year. Still, EPS has barely risen at all in aggregate from three years ago, which is not ideal. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

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 Qingdao Foods 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. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

What We Can Learn From Qingdao Foods' 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.

As we suspected, our examination of Qingdao Foods 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.
