With a price-to-earnings (or "P/E") ratio of 15.2x Great Wall Motor Company Limited (HKG:2333) may be sending very bearish signals at the moment, given that almost half of all companies in Hong Kong have P/E ratios under 9x and even P/E's lower than 5x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

Recent times haven't been advantageous for Great Wall Motor as its earnings have been falling quicker than most other companies. It might be that many expect the dismal earnings performance to recover substantially, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Great Wall Motor's Growth Trending?

In order to justify its P/E ratio, Great Wall Motor 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 45%. Still, the latest three year period has seen an excellent 34% overall rise in EPS, in spite of its unsatisfying short-term performance. 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 31% per annum as estimated by the analysts watching the company. With the market only predicted to deliver 16% each year, the company is positioned for a stronger earnings result.

In light of this, it's understandable that Great Wall Motor's P/E sits above the majority of other companies. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

The Key Takeaway

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.
