Hefei Meyer Optoelectronic Technology Inc.'s (SZSE:002690) price-to-earnings (or "P/E") ratio of 21.1x might make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 30x and even P/E's above 55x 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 limited.

While the market has experienced earnings growth lately, Hefei Meyer Optoelectronic Technology's earnings have gone into reverse gear, which is not great. The P/E is probably low because investors think this poor earnings performance isn't going to get any better. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

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

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

Retrospectively, the last year delivered a frustrating 2.8% decrease to the company's bottom line. However, a few very strong years before that means that it was still able to grow EPS by an impressive 42% in total over the last three years. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Turning to the outlook, the next three years should generate growth of 14% per annum as estimated by the ten analysts watching the company. That's shaping up to be materially lower than the 21% per annum growth forecast for the broader market.

With this information, we can see why Hefei Meyer Optoelectronic Technology is trading at a P/E lower than the market. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.

The Final Word
