Demystifying the P/E ratio

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

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

SAU Price-Earnings Ratio = A$0.24 ÷ A$0.046 = 5.3x

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 SAU, such as capital structure and profitability. A common peer group is companies that exist in the same industry, which is what I use. At 5.3x, SAU’s P/E is lower than its industry peers (13.7x). This implies that investors are undervaluing each dollar of SAU’s earnings. Therefore, according to this analysis, SAU is an under-priced stock.

Assumptions to watch out for

While our conclusion might prompt you to buy SAU immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to SAU, or else the difference in P/E might be a result of other factors. For example, if you compared lower risk firms with SAU, 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 SAU to are fairly valued by the market. If this does not hold true, SAU’s lower P/E ratio may be because firms in our peer group are overvalued by the market.
