When close to half the companies in China have price-to-earnings ratios (or "P/E's") below 31x, you may consider Shandong Kaisheng New Materials Co.,Ltd. (SZSE:301069) as a stock to avoid entirely with its 77.9x P/E ratio. 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.

Earnings have risen firmly for Shandong Kaisheng New MaterialsLtd recently, which is pleasing to see. 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

Shandong Kaisheng New MaterialsLtd's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered an exceptional 16% gain to the company's bottom line. Still, incredibly EPS has fallen 70% in total from three years ago, which is quite disappointing. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 38% shows it's an unpleasant look.

With this information, we find it concerning that Shandong Kaisheng New MaterialsLtd is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. 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

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

Our examination of Shandong Kaisheng New MaterialsLtd 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.
