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 PRO

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

PRO Price-Earnings Ratio = PLN3.9 ÷ PLN0.842 = 4.6x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. Our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to PRO, such as company lifetime and products sold. A common peer group is companies that exist in the same industry, which is what I use. PRO’s P/E of 4.6x is lower than its industry peers (12.7x), which implies that each dollar of PRO’s earnings is being undervalued by investors. As such, our analysis shows that PRO represents an under-priced stock.

Assumptions to watch out for

However, before you rush out to buy PRO, it is important to note that this conclusion is based on two key assumptions. Firstly, our peer group contains companies that are similar to PRO. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with PRO, 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 PRO to are fairly valued by the market. If this does not hold, there is a possibility that PRO’s P/E is lower because our peer group is overvalued by the market.
