There wouldn't be many who think Jiangsu Expressway Company Limited's (HKG:177) price-to-earnings (or "P/E") ratio of 8.9x is worth a mention when the median P/E in Hong Kong is similar at about 9x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

Jiangsu Expressway certainly has been doing a good job lately as it's been growing earnings more than most other companies. One possibility is that the P/E is moderate because investors think this strong earnings performance might be about to tail off. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

Is There Some Growth For Jiangsu Expressway?

There's an inherent assumption that a company should be matching the market for P/E ratios like Jiangsu Expressway's to be considered reasonable.

Retrospectively, the last year delivered a decent 7.8% gain to the company's bottom line. EPS has also lifted 22% in aggregate from three years ago, partly thanks to the last 12 months of growth. Accordingly, shareholders would have probably been satisfied with the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 6.6% each year during the coming three years according to the seven analysts following the company. With the market predicted to deliver 16% growth per year, the company is positioned for a weaker earnings result.

In light of this, it's curious that Jiangsu Expressway's P/E sits in line with the majority of other companies. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. Maintaining these prices will be difficult to achieve as this level of earnings growth is likely to weigh down the shares eventually.

The Key Takeaway

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of Jiangsu Expressway's analyst forecasts revealed that its inferior earnings outlook isn't impacting its P/E as much as we would have predicted. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
