TangShan Port Group Co.,Ltd's (SHSE:601000) price-to-earnings (or "P/E") ratio of 12.6x might make it look like a strong 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 highly reduced P/E.

With its earnings growth in positive territory compared to the declining earnings of most other companies, TangShan Port GroupLtd has been doing quite well of late. One possibility is that the P/E is low because investors think the company's earnings are going to fall away like everyone else's soon. 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 out of favour.

What Are Growth Metrics Telling Us About The Low P/E?

TangShan Port GroupLtd's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

If we review the last year of earnings growth, the company posted a worthy increase of 11%. Still, EPS has barely risen at all in aggregate from three years ago, which is not ideal. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Turning to the outlook, the next year should generate growth of 18% as estimated by the three analysts watching the company. With the market predicted to deliver 41% growth , the company is positioned for a weaker earnings result.

In light of this, it's understandable that TangShan Port GroupLtd's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Key Takeaway

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

We've established that TangShan Port GroupLtd maintains its low P/E on the weakness of its forecast growth being lower than the wider market, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
