Hubei Jiuzhiyang Infrared System Co., Ltd's (SZSE:300516) price-to-earnings (or "P/E") ratio of 64.5x 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 27x 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.

Earnings have risen at a steady rate over the last year for Hubei Jiuzhiyang Infrared System, which is generally not a bad outcome. One possibility is that the P/E is high because investors think this good earnings growth will be enough to outperform the broader market in the near future. 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 Hubei Jiuzhiyang Infrared System's to be considered reasonable.

If we review the last year of earnings growth, the company posted a worthy increase of 5.5%. However, due to its less than impressive performance prior to this period, EPS growth is practically non-existent over the last three years overall. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

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

In light of this, it's alarming that Hubei Jiuzhiyang Infrared System'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. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Hubei Jiuzhiyang Infrared System 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.
