With a price-to-earnings (or "P/E") ratio of 43.8x Dongguan Golden Sun Abrasives Co.,Ltd (SZSE:300606) may be sending very bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 28x and even P/E's lower than 17x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Recent times have been quite advantageous for Dongguan Golden Sun AbrasivesLtd as its earnings have been rising very briskly. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Dongguan Golden Sun AbrasivesLtd's Growth Trending?

In order to justify its P/E ratio, Dongguan Golden Sun AbrasivesLtd would need to produce outstanding growth well in excess of the market.

Retrospectively, the last year delivered an exceptional 215% gain to the company's bottom line. However, this wasn't enough as the latest three year period has seen a very unpleasant 16% drop in EPS in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 36% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's alarming that Dongguan Golden Sun AbrasivesLtd's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Final Word

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Dongguan Golden Sun AbrasivesLtd revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. 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.

Having said that, be aware Dongguan Golden Sun AbrasivesLtd is showing 3 warning signs in our investment analysis, and 1 of those is potentially serious.
