Huachangda Intelligent Equipment Group Co.,Ltd.'s (SZSE:300278) price-to-earnings (or "P/E") ratio of 54.3x might make it look like a strong sell right now compared to the market in China, where around half of the companies have P/E ratios below 26x and even P/E's below 16x are quite common. 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.

For example, consider that Huachangda Intelligent Equipment GroupLtd's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

How Is Huachangda Intelligent Equipment GroupLtd's Growth Trending?

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

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 29%. Unfortunately, that's brought it right back to where it started three years ago with EPS growth being virtually non-existent overall during that time. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 36% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that Huachangda Intelligent Equipment GroupLtd is trading at a P/E higher than the market. 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 good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Bottom Line On Huachangda Intelligent Equipment GroupLtd's P/E

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 Huachangda Intelligent Equipment GroupLtd revealed its three-year earnings trends aren't impacting its high P/E anywhere near 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 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.
