When close to half the companies in China have price-to-earnings ratios (or "P/E's") below 32x, you may consider ShanDongDenghai Seeds Co.,Ltd (SZSE:002041) as a stock to potentially avoid with its 39.9x P/E ratio. However, the P/E might be 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, ShanDongDenghai SeedsLtd 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?

ShanDongDenghai SeedsLtd's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than 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 7.3%. Even so, admirably EPS has lifted 36% in aggregate from three years ago, notwithstanding the last 12 months. 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 year should generate growth of 46% as estimated by the four analysts watching the company. That's shaping up to be materially higher than the 38% growth forecast for the broader market.

With this information, we can see why ShanDongDenghai SeedsLtd 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 Key Takeaway
