Eoptolink Technology Inc., Ltd.'s (SZSE:300502) price-to-earnings (or "P/E") ratio of 64.3x might make it look like a strong sell right now compared to the market in China, where around half of the companies have P/E ratios below 34x and even P/E's below 20x are quite common. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

With earnings that are retreating more than the market's of late, Eoptolink Technology has been very sluggish. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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

In order to justify its P/E ratio, Eoptolink Technology would need to produce outstanding growth well in excess of 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 40%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 32% in total over the last three years. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Shifting to the future, estimates from the ten analysts covering the company suggest earnings should grow by 88% over the next year. That's shaping up to be materially higher than the 44% growth forecast for the broader market.

With this information, we can see why Eoptolink Technology is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

The Final Word

As we suspected, our examination of Eoptolink Technology's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E.

It's hard to see the share price falling strongly in the near future under these circumstances.
