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.

Formula

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

P/E Calculation for NPI

Price per share = CA$24.89

Earnings per share = CA$1.17

∴ Price-Earnings Ratio = CA$24.89 ÷ CA$1.17 = 21.3x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful 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 NPI, 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 similar companies should technically have similar P/E ratios, we can very quickly come to some conclusions about the stock if the ratios differ.

NPI’s P/E of 21.3x is lower than its industry peers (52.1x), which implies that each dollar of NPI’s earnings is being undervalued by investors. This multiple is a median of profitable companies of 7 Renewable Energy companies in CA including Pattern Energy Group, Capital Power and Polaris Infrastructure. As such, our analysis shows that NPI represents an under-priced stock.

Assumptions to be aware of

While our conclusion might prompt you to buy NPI 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 NPI. 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 NPI, then NPI’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 NPI, NPI’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 NPI to are fairly valued by the market. If this does not hold, there is a possibility that NPI’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 NPI 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.
