P/E is a popular ratio used for 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 CAAP

Price per share = $9.84

Earnings per share = $0.384

∴ Price-Earnings Ratio = $9.84 ÷ $0.384 = 25.6x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. Ideally, we want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as CAAP, such as size and country of operation. A common peer group is companies that exist in the same industry, which is what I use below. 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 CAAP’s P/E of 25.6x is higher than its industry peers (17.5x), it means that investors are paying more than they should for each dollar of CAAP’s earnings. This multiple is a median of profitable companies of 25 Infrastructure companies in US including COSCO SHIPPING Ports, COSCO SHIPPING Ports and OHL México. de. Therefore, according to this analysis, CAAP is an over-priced stock.

Assumptions to watch out for

Before you jump to the conclusion that CAAP should be banished from your portfolio, it is important to realise that our conclusion rests on two important assertions. The first is that our “similar companies” are actually similar to CAAP. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you accidentally compared lower growth firms with CAAP, then CAAP’s P/E would naturally be higher since investors would reward CAAP’s higher growth with a higher price. Alternatively, if you inadvertently compared riskier firms with CAAP, CAAP’s P/E would again be higher since investors would reward CAAP’s lower risk with a higher price as well. The second assumption that must hold true is that the stocks we are comparing CAAP to are fairly valued by the market. If this assumption does not hold true, CAAP’s higher P/E ratio may be because firms in our peer group are being undervalued by the market.

What this means for you:

Since you may have already conducted your due diligence on CAAP, the overvaluation of the stock may mean it is a good time to reduce 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.
