# Is Zhejiang Expressway Co Ltd (HKG:576) Attractive At This PE Ratio?

The content of this article will benefit those of you who are starting to educate yourself about investing in the stock market and want to start learning about core concepts of fundamental analysis on practical examples from today’s market.

Zhejiang Expressway Co Ltd (HKG:576) is trading with a trailing P/E of 7.5x, which is lower than the industry average of 8.8x. While this makes 576 appear like a great stock to buy, you might change your mind after I explain the assumptions behind the P/E ratio. In this article, I will explain what the P/E ratio is as well as what you should look out for when using it.

### Breaking down the P/E ratio

A common ratio used for relative valuation is the P/E ratio. It compares a stock’s price per share to the stock’s earnings per share. A more intuitive way of understanding the P/E ratio is to think of it as how much investors are paying for each dollar of the company’s earnings.

Formula

Price-Earnings Ratio = Price per share ÷ Earnings per share

P/E Calculation for 576

Price per share = CN¥5.57

Earnings per share = CN¥0.744

∴ Price-Earnings Ratio = CN¥5.57 ÷ CN¥0.744 = 7.5x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. Ultimately, our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to 576, such as company lifetime and products sold. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. Since it is expected that similar companies have similar P/E ratios, we can come to some conclusions about the stock if the ratios are different.

Since 576’s P/E of 7.5x is lower than its industry peers (8.8x), it means that investors are paying less than they should for each dollar of 576’s earnings. This multiple is a median of profitable companies of 22 Infrastructure companies in HK including China Dredging Environment Protection Holdings, COSCO SHIPPING Ports and Qilu Expressway. Therefore, according to this analysis, 576 is an under-priced stock.

### A few caveats

While our conclusion might prompt you to buy 576 immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to 576. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you accidentally compared higher growth firms with 576, then 576’s P/E would naturally be lower since investors would reward its peers’ higher growth with a higher price. Alternatively, if you inadvertently compared less risky firms with 576, 576’s P/E would again be lower since investors would reward its peers’ lower risk with a higher price as well. The second assumption that must hold true is that the stocks we are comparing 576 to are fairly valued by the market. If this assumption does not hold true, 576’s lower P/E ratio may be because firms in our peer group are being overvalued by the market.

### What this means for you:

You may have already conducted fundamental analysis on the stock as a shareholder, so its current undervaluation could signal a good buying opportunity to increase your exposure to 576. Now that you understand the ins and outs of the PE metric, you should know to bear in mind its limitations before you make an investment decision. Remember that basing your investment decision off one metric alone is certainly not sufficient. There are many things I have not taken into account in this article and the PE ratio is very one-dimensional.
