Should You Be Tempted To Buy Edison SA. (WSE:EDN) At Its Current PE Ratio?

Gerald Huddleston

Edison SA. (WSE:EDN) is currently trading at a trailing P/E of 2.2x, which is lower than the industry average of 24.9x. While EDN might seem like an attractive stock to buy, it is important to understand the assumptions behind the P/E ratio before you make any investment decisions. Today, I will deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio. See our latest analysis for Edison

Demystifying the P/E ratio

WSE:EDN PE PEG Gauge May 9th 18

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 dollar of the company’s earnings.

P/E Calculation for EDN

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

EDN Price-Earnings Ratio = PLN1.84 ÷ PLN0.845 = 2.2x

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. Our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to EDN, such as company lifetime and products sold. A common peer group is companies that exist in the same industry, which is what I use. EDN’s P/E of 2.2x is lower than its industry peers (24.9x), which implies that each dollar of EDN’s earnings is being undervalued by investors. As such, our analysis shows that EDN represents an under-priced stock.

Assumptions to be aware of

However, before you rush out to buy EDN, it is important to note that this conclusion is based on two key assumptions. The first is that our “similar companies” are actually similar to EDN, or else the difference in P/E might be a result of other factors. For example, if you compared lower risk firms with EDN, 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 EDN to are fairly valued by the market. If this is violated, EDN’s P/E may be lower than its peers as they are actually overvalued by investors.

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 EDN 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. There are many things I have not taken into account in this article and the PE ratio is very one-dimensional.
