P/E is often used for relative valuation since earnings power is a chief driver of investment value. 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 STZ

Price per share = $210.23

Earnings per share = $13.739

∴ Price-Earnings Ratio = $210.23 ÷ $13.739 = 15.3x

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. We preferably want to compare the stock’s P/E ratio to the average of companies that have similar features to STZ, such as capital structure and profitability. 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.

STZ’s P/E of 15.3x is lower than its industry peers (23.4x), which implies that each dollar of STZ’s earnings is being undervalued by investors. This multiple is a median of profitable companies of 23 Beverage companies in US including Rocky Mountain International, Bebida Beverage and RushNet. Therefore, according to this analysis, STZ is an under-priced stock.

Assumptions to watch out for

While our conclusion might prompt you to buy STZ 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 STZ. If this isn’t the case, the difference in P/E could be due to some other factors. For example, if you accidentally compared higher growth firms with STZ, then STZ’s P/E would naturally be lower since investors would reward its peers’ higher growth with a higher price. Alternatively, if you inadvertently compared less risky firms with STZ, STZ’s P/E would again be lower since investors would reward its peers’ lower risk with a higher price as well. The second assumption that must hold true is that the stocks we are comparing STZ to are fairly valued by the market. If this does not hold, there is a possibility that STZ’s P/E is lower because firms in our peer group are being overvalued by the market.

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 STZ to your portfolio. But keep in mind that the usefulness of relative valuation depends on whether you are comfortable with making the assumptions I mentioned above. Remember that basing your investment decision off one metric alone is certainly not sufficient.
