China South Publishing & Media Group Co., Ltd's (SHSE:601098) price-to-earnings (or "P/E") ratio of 13.9x 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 35x and even P/E's above 69x 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.

China South Publishing & Media Group certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. 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?

The only time you'd be truly comfortable seeing a P/E as depressed as China South Publishing & Media Group's is when the company's growth is on track to lag the market decidedly.

Taking a look back first, we see that there was hardly any earnings per share growth to speak of for the company over the past year. Still, the latest three year period was better as it's delivered a decent 9.7% overall rise in EPS. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Shifting to the future, estimates from the four analysts covering the company suggest earnings growth is heading into negative territory, declining 5.7% over the next year. That's not great when the rest of the market is expected to grow by 39%.

In light of this, it's understandable that China South Publishing & Media Group's P/E would sit below the majority of other companies. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

The Key Takeaway

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 China South Publishing & Media Group maintains its low P/E on the weakness of its forecast for sliding earnings, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. It's hard to see the share price rising strongly in the near future under these circumstances.
