The P/E ratio is a popular ratio used in relative valuation since earnings power is a key driver of investment value. By comparing a stock’s price per share to its earnings per share, we are able to see how much investors are paying for each dollar of the company’s earnings.


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

P/E Calculation for 258

Price per share = HK$3.29

Earnings per share = HK$0.694

∴ Price-Earnings Ratio = HK$3.29 ÷ HK$0.694 = 4.7x

On its own, the P/E ratio doesn’t tell you much; however, it becomes extremely useful when you compare it with 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 258, 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 similar companies should technically have similar P/E ratios, we can very quickly come to some conclusions about the stock if the ratios differ.

Since 258’s P/E of 4.7x is lower than its industry peers (7.3x), it means that investors are paying less than they should for each dollar of 258’s earnings. As such, our analysis shows that 258 represents an under-priced stock.

Assumptions to watch out for

While our conclusion might prompt you to buy 258 immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to 258. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you are inadvertently comparing lower risk firms with 258, then 258’s P/E would naturally be lower than its peers, since investors would value those with lower risk with a higher price. The other possibility is if you were accidentally comparing higher growth firms with 258. In this case, 258’s P/E would be lower since investors would also reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing 258 to are fairly valued by the market. If this does not hold, there is a possibility that 258’s P/E is lower because firms in our peer group are being overvalued by the market.

What this means for you:

If your personal research into the stock confirms what the P/E ratio is telling you, it might be a good time to add more of 258 to your portfolio. But keep in mind that the usefulness of relative valuation depends on whether you are comfortable with making the assumptions I mentioned above. Remember that basing your investment decision off one metric alone is certainly not sufficient.
