With a price-to-earnings (or "P/E") ratio of 23.6x Shenzhen Lifotronic Technology Co., Ltd. (SHSE:688389) may be sending bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 32x and even P/E's higher than 58x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

Recent times have been advantageous for Shenzhen Lifotronic Technology as its earnings have been rising faster than most other companies. One possibility is that the P/E is low because investors think this strong earnings performance might be less impressive moving forward. 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?

In order to justify its P/E ratio, Shenzhen Lifotronic Technology would need to produce sluggish growth that's trailing the market.

If we review the last year of earnings growth, the company posted a terrific increase of 28%. The strong recent performance means it was also able to grow EPS by 126% in total over the last three years. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Shifting to the future, estimates from the three analysts covering the company suggest earnings should grow by 27% per annum over the next three years. With the market only predicted to deliver 20% per annum, the company is positioned for a stronger earnings result.

With this information, we find it odd that Shenzhen Lifotronic Technology is trading at a P/E lower than the market. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

The Final Word

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Shenzhen Lifotronic Technology's analyst forecasts revealed that its superior earnings outlook isn't contributing to its P/E anywhere near as much as we would have predicted. When we see a strong earnings outlook with faster-than-market growth, we assume potential risks are what might be placing significant pressure on the P/E ratio. It appears many are indeed anticipating earnings instability, because these conditions should normally provide a boost to the share price.
