Breaking down the P/E ratio

The P/E ratio is one of many ratios used in relative valuation. 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.


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

P/E Calculation for DIA

Price per share = €3.53

Earnings per share = €0.214

∴ Price-Earnings Ratio = €3.53 ÷ €0.214 = 16.5x

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. We preferably want to compare the stock’s P/E ratio to the average of companies that have similar features to DIA, such as capital structure and profitability. 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.

DIA’s P/E of 16.5x is lower than its industry peers (19x), which implies that each dollar of DIA’s earnings is being undervalued by investors. Therefore, according to this analysis, DIA is an under-priced stock.

Assumptions to watch out for

However, before you rush out to buy DIA, it is important to note that this conclusion is based on two key assumptions. The first is that our peer group actually contains companies that are similar to DIA. If this isn’t the case, the difference in P/E could be due to some other factors. For example, if you are inadvertently comparing lower risk firms with DIA, then DIA’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 DIA. In this case, DIA’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 DIA to are fairly valued by the market. If this does not hold, there is a possibility that DIA’s P/E is lower because firms in our peer group are being overvalued by the market.

What this means for you:

Since you may have already conducted your due diligence on DIA, the undervaluation of the stock may mean it is a good time to top up on your current holdings. But at the end of the day, keep in mind that relative valuation relies heavily on critical assumptions I’ve outlined above. Remember that basing your investment decision off one metric alone is certainly not sufficient.
