With a price-to-earnings (or "P/E") ratio of 18.9x Ningbo United Group Co.,Ltd. (SHSE:600051) 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 58x 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 Ningbo United GroupLtd over the last year, which is not ideal at all. 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?

Ningbo United GroupLtd's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than 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 3.2%. That put a dampener on the good run it was having over the longer-term as its three-year EPS growth is still a noteworthy 15% in total. So we can start by confirming that the company has generally done a good job of growing earnings over that time, even though it had some hiccups along the way.

Comparing that to the market, which is predicted to deliver 36% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

With this information, we can see why Ningbo United GroupLtd is trading at a P/E lower than the market. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Final Word

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Ningbo United GroupLtd revealed its three-year earnings trends are contributing to its low P/E, given they look worse than current market expectations. 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 rising strongly in the near future under these circumstances.
