Breaking down the P/E ratio

A common ratio used for relative valuation is the P/E ratio. 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 AER

Price per share = $55.33

Earnings per share = $6.953

∴ Price-Earnings Ratio = $55.33 ÷ $6.953 = 8x

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 AER, such as company lifetime and products sold. 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.

At 8x, AER’s P/E is lower than its industry peers (14.6x). This implies that investors are undervaluing each dollar of AER’s earnings. This multiple is a median of profitable companies of 24 Trade Distributors companies in US including Star Struck, Spicers and General Steel Holdings. As such, our analysis shows that AER represents an under-priced stock.

Assumptions to watch out for

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