Gansu Yasheng Industrial (Group) Co., Ltd.'s (SHSE:600108) price-to-earnings (or "P/E") ratio of 69x 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 30x and even P/E's below 18x 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.

Gansu Yasheng Industrial (Group) has been doing a good job lately as it's been growing earnings at a solid pace. It might be that many expect the respectable earnings performance to beat most other companies over the coming period, which has increased investors' willingness to pay up for the stock. If not, then existing shareholders may be a little nervous about the viability of the share price.

How Is Gansu Yasheng Industrial (Group)'s Growth Trending?

The only time you'd be truly comfortable seeing a P/E as steep as Gansu Yasheng Industrial (Group)'s is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered an exceptional 21% gain to the company's bottom line. The latest three year period has also seen an excellent 109% overall rise in EPS, aided by its short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.

This is in contrast to the rest of the market, which is expected to grow by 41% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that Gansu Yasheng Industrial (Group)'s P/E sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Bottom Line On Gansu Yasheng Industrial (Group)'s P/E

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of Gansu Yasheng Industrial (Group) revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. 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.
