AviChina Industry & Technology Company Limited's (HKG:2357) price-to-earnings (or "P/E") ratio of 11.3x might make it look like a sell right now compared to the market in Hong Kong, where around half of the companies have P/E ratios below 9x and even P/E's below 5x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

AviChina Industry & Technology's earnings growth of late has been pretty similar to most other companies. One possibility is that the P/E is high because investors think this modest earnings performance will accelerate. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

There's an inherent assumption that a company should outperform the market for P/E ratios like AviChina Industry & Technology's to be considered reasonable.

Retrospectively, the last year delivered a decent 3.3% gain to the company's bottom line. EPS has also lifted 23% in aggregate from three years ago, partly thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been respectable for the company.

Turning to the outlook, the next three years should generate growth of 15% per year as estimated by the five analysts watching the company. With the market predicted to deliver 15% growth per annum, the company is positioned for a comparable earnings result.

With this information, we find it interesting that AviChina Industry & Technology is trading at a high P/E compared to the market. Apparently many investors in the company are more bullish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.

The Final Word

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.

When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower.
