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 WBA

Price per share = $67.24

Earnings per share = $4.004

∴ Price-Earnings Ratio = $67.24 ÷ $4.004 = 16.8x

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. Ideally, we want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as WBA, such as size and country of operation. 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 16.8x, WBA’s P/E is lower than its industry peers (21.2x). This implies that investors are undervaluing each dollar of WBA’s earnings. As such, our analysis shows that WBA represents an under-priced stock.

Assumptions to watch out for

However, before you rush out to buy WBA, it is important to note that this conclusion is based on two key assumptions. The first is that our “similar companies” are actually similar to WBA. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you are inadvertently comparing lower risk firms with WBA, then WBA’s P/E would naturally be lower than its peers, since investors would value those with lower risk with a higher price. The other possibility is if you were accidentally comparing higher growth firms with WBA. In this case, WBA’s P/E would be lower since investors would also reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing WBA to are fairly valued by the market. If this assumption is violated, WBA’s P/E may be lower than its peers because its peers are actually overvalued by investors.

What this means for you:

If your personal research into the stock confirms what the P/E ratio is telling you, it might be a good time to add more of WBA to your portfolio.

Remember that basing your investment decision off one metric alone is certainly not sufficient.
