The P/E ratio is one of many ratios used in relative valuation. It compares a stock’s price per share to the stock’s earnings per share. A more intuitive way of understanding the P/E ratio is to think of it as how much investors are paying for each dollar of the company’s earnings.

P/E Calculation for PMBC

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

PMBC Price-Earnings Ratio = $9.7 ÷ $0.451 = 21.5x

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 PMBC, such as company lifetime and products sold. A common peer group is companies that exist in the same industry, which is what I use. At 21.5x, PMBC’s P/E is higher than its industry peers (17.5x). This implies that investors are overvaluing each dollar of PMBC’s earnings. As such, our analysis shows that PMBC represents an over-priced stock.

A few caveats

While our conclusion might prompt you to sell your PMBC shares immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to PMBC, or else the difference in P/E might be a result of other factors. For example, if you are comparing lower risk firms with PMBC, then its P/E would naturally be lower than its peers, as investors would value those with lower risk at a higher price. The second assumption that must hold true is that the stocks we are comparing PMBC to are fairly valued by the market. If this does not hold, there is a possibility that PMBC’s P/E is lower because our peer group is overvalued by the market.
