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

Price per share = PLN12.8

Earnings per share = PLN2.765

∴ Price-Earnings Ratio = PLN12.8 ÷ PLN2.765 = 4.6x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. We preferably want to compare the stock’s P/E ratio to the average of companies that have similar features to PRL, such as capital structure and profitability. One way of gathering a peer group is to use firms in the same industry, which is what I’ll 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 PRL’s P/E of 4.6x is lower than its industry peers (17.1x), it means that investors are paying less than they should for each dollar of PRL’s earnings. As such, our analysis shows that PRL represents an under-priced stock.

Assumptions to be aware of

While our conclusion might prompt you to buy PRL immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to PRL. 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 PRL, then PRL’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 PRL, PRL’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 PRL to are fairly valued by the market. If this assumption does not hold true, PRL’s lower P/E ratio may be because firms in our peer group are being overvalued by the market.
