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 pound of the company’s earnings.

P/E Calculation for PMO

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

PMO Price-Earnings Ratio = $1.33 ÷ $0.011 = 116.8x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. Our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to PMO, such as company lifetime and products sold. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. Since PMO’s P/E of 116.8x is higher than its industry peers (14.5x), it means that investors are paying more than they should for each dollar of PMO’s earnings. Therefore, according to this analysis, PMO is an over-priced stock.

Assumptions to watch out for

While our conclusion might prompt you to sell your PMO shares immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to PMO, or else the difference in P/E might be a result of other factors. For example, if you compared lower risk firms with PMO, then investors would naturally value it at a lower price since it is a riskier investment. The second assumption that must hold true is that the stocks we are comparing PMO to are fairly valued by the market. If this is violated, PMO’s P/E may be lower than its peers as they are actually overvalued by investors.
