With a price-to-earnings (or "P/E") ratio of 16.3x Transfar Zhilian Co., Ltd. (SZSE:002010) may be sending bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 30x and even P/E's higher than 53x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

As an illustration, earnings have deteriorated at Transfar Zhilian over the last year, which is not ideal at all. One possibility is that the P/E is low because investors think the company won't do enough to avoid underperforming the broader market in the near future. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

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

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

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 18%. This means it has also seen a slide in earnings over the longer-term as EPS is down 45% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 35% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we are not surprised that Transfar Zhilian 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. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

The Final Word

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 Transfar Zhilian maintains its low P/E on the weakness of its sliding earnings over the medium-term, 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. If recent medium-term earnings trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.
