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.

Formula

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

P/E Calculation for SWUT

Price per share = €10.8

Earnings per share = €1.691

∴ Price-Earnings Ratio = €10.8 ÷ €1.691 = 6.4x

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 SWUT, such as company lifetime and products sold. 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.

At 6.4x, SWUT’s P/E is lower than its industry peers (15.9x). This implies that investors are undervaluing each dollar of SWUT’s earnings. As such, our analysis shows that SWUT represents an under-priced stock.

A few caveats

While our conclusion might prompt you to buy SWUT immediately, there are two important assumptions you should be aware of. The first is that our peer group actually contains companies that are similar to SWUT. If this isn’t the case, the difference in P/E could be due to some other factors. For example, if you inadvertently compared lower risk firms with SWUT, then investors would naturally value SWUT at a lower price since it is a riskier investment. Similarly, if you accidentally compared higher growth firms with SWUT, investors would also value SWUT at a lower price since it is a lower growth investment. Both scenarios would explain why SWUT has a lower P/E ratio than its peers. The second assumption that must hold true is that the stocks we are comparing SWUT to are fairly valued by the market. If this assumption does not hold true, SWUT’s lower P/E ratio may be because firms in our peer group are being overvalued by the market.
