Ways Electron Co.,Ltd. (SHSE:605218) shares have retraced a considerable 33% in the last month, reversing a fair amount of their solid recent performance. Looking back over the past twelve months the stock has been a solid performer regardless, with a gain of 11%.

Although its price has dipped substantially, Ways ElectronLtd may still be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 45.9x, since almost half of all companies in China have P/E ratios under 26x and even P/E's lower than 16x 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.

For instance, Ways ElectronLtd's receding earnings in recent times would have to be some food for thought. It might be that many expect the company to still outplay most other companies over the coming period, 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.

Does Growth Match The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Ways ElectronLtd's to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 3.0%. As a result, earnings from three years ago have also fallen 24% overall. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 42% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's alarming that Ways ElectronLtd's P/E sits above the majority of other companies. 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 Bottom Line On Ways ElectronLtd's P/E

Even after such a strong price drop, Ways ElectronLtd's P/E still exceeds the rest of the market significantly. 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.

We've established that Ways ElectronLtd currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, 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.
