Xiamen Guang Pu Electronics Co., Ltd.'s (SZSE:300632) price-to-earnings (or "P/E") ratio of 36.7x might make it look like a sell right now compared to the market in China, where around half of the companies have P/E ratios below 28x and even P/E's below 17x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

Recent times have been quite advantageous for Xiamen Guang Pu Electronics as its earnings have been rising very briskly. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders might be a little nervous about the viability of the share price.

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

There's an inherent assumption that a company should outperform the market for P/E ratios like Xiamen Guang Pu Electronics' to be considered reasonable.

Retrospectively, the last year delivered an exceptional 80% gain to the company's bottom line. However, this wasn't enough as the latest three year period has seen a very unpleasant 48% drop in EPS in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

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

With this information, we find it concerning that Xiamen Guang Pu Electronics is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Key Takeaway

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 Xiamen Guang Pu Electronics revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
