Breaking down the P/E ratio

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.

P/E Calculation for IBE

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

IBE Price-Earnings Ratio = €6 ÷ €0.478 = 12.6x

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 want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as IBE, such as size and country of operation. A common peer group is companies that exist in the same industry, which is what I use. Since IBE’s P/E of 12.6x is lower than its industry peers (13.9x), it means that investors are paying less than they should for each dollar of IBE’s earnings. Therefore, according to this analysis, IBE is an under-priced stock.

Assumptions to be aware of

Before you jump to the conclusion that IBE is the perfect buying opportunity, it is important to realise that our conclusion rests on two assertions. The first is that our “similar companies” are actually similar to IBE, or else the difference in P/E might be a result of other factors. For example, if you are comparing lower risk firms with IBE, then its P/E would naturally be lower than its peers, as investors would value those with lower risk at a higher price. The second assumption that must hold true is that the stocks we are comparing IBE to are fairly valued by the market. If this is violated, IBE’s P/E may be lower than its peers as they are actually overvalued by investors.
