With a price-to-earnings (or "P/E") ratio of 21.3x CMST Development Co.,Ltd. (SHSE:600787) may be sending bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 35x and even P/E's higher than 65x 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.

For instance, CMST DevelopmentLtd's receding earnings in recent times would have to be some food for thought. 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. 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.

How Is CMST DevelopmentLtd's Growth Trending?

There's an inherent assumption that a company should underperform the market for P/E ratios like CMST DevelopmentLtd's to be considered reasonable.

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 29%. Even so, admirably EPS has lifted 81% in aggregate from three years ago, notwithstanding the last 12 months. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 44% 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 CMST DevelopmentLtd 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.
