To the annoyance of some shareholders, Shandong Kehui Power Automation Co.,Ltd. (SHSE:688681) shares are down a considerable 27% in the last month, which continues a horrid run for the company. To make matters worse, the recent drop has wiped out a year's worth of gains with the share price now back where it started a year ago.

Although its price has dipped substantially, there still wouldn't be many who think Shandong Kehui Power AutomationLtd's price-to-earnings (or "P/E") ratio of 24.7x is worth a mention when the median P/E in China is similar at about 26x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

As an illustration, earnings have deteriorated at Shandong Kehui Power AutomationLtd over the last year, which is not ideal at all. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If not, then existing shareholders may be a little nervous about the viability of the share price.

How Is Shandong Kehui Power AutomationLtd's Growth Trending?

Shandong Kehui Power AutomationLtd's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 26%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 108% in total over the last three years. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 35% shows it's noticeably less attractive on an annualised basis.

With this information, we find it interesting that Shandong Kehui Power AutomationLtd is trading at a fairly similar P/E to the market. It seems most investors are ignoring the fairly limited recent growth rates and are willing to pay up for exposure to the stock. They may be setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Final Word

Following Shandong Kehui Power AutomationLtd's share price tumble, its P/E is now hanging on to the median market P/E. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Shandong Kehui Power AutomationLtd revealed its three-year earnings trends aren't impacting its P/E 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 moderate P/E lower. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
