# Is Rafako SA’s (WSE:RFK) PE Ratio A Signal To Sell For Investors?

The content of this article will benefit those of you who are starting to educate yourself about investing in the stock market and want to begin learning about how to value company based on its current earnings and what are the drawbacks of this method.

Rafako SA (WSE:RFK) is trading with a trailing P/E of 26.3, which is higher than the industry average of 9.2. While this might not seem positive, it is important to understand the assumptions behind the P/E ratio before you make any investment decisions. Today, I will explain what the P/E ratio is as well as what you should look out for when using it.

### Breaking down the P/E ratio

P/E is a popular ratio used for 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.

Formula

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

P/E Calculation for RFK

Price per share = PLN2.1

Earnings per share = PLN0.0798

∴ Price-Earnings Ratio = PLN2.1 ÷ PLN0.0798 = 26.3x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. Ultimately, our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to RFK, such as company lifetime and products sold. A common peer group is companies that exist in the same industry, which is what I use below. Since similar companies should technically have similar P/E ratios, we can very quickly come to some conclusions about the stock if the ratios differ.

RFK’s P/E of 26.3 is higher than its industry peers (9.2), which implies that each dollar of RFK’s earnings is being overvalued by investors. This multiple is a median of profitable companies of 16 Machinery companies in PL including Zastal, Fabryki Sprzetu i Narzedzi Górniczych Grupa Kapitalowa FASING and MOJ Spólka Akcyjna. You could also say that the market is suggesting that RFK has a stronger business than the average comparable company.

### Assumptions to watch out for

However, it is important to note that our examination of the stock is based on certain assumptions. The first is that our “similar companies” are actually similar to RFK. If not, the difference in P/E might be a result of other factors. For example, Rafako SA could be growing more quickly than the companies we’re comparing it with. In that case it would deserve a higher P/E ratio. Of course, it is possible that the stocks we are comparing with RFK are not fairly valued. Thus while we might conclude that it is richly valued relative to its peers, that could be explained by the peer group being undervalued.

### What this means for you:

You may have already conducted fundamental analysis on the stock as a shareholder, so its current overvaluation could signal a potential selling opportunity to reduce your exposure to RFK. Now that you understand the ins and outs of the PE metric, you should know to bear in mind its limitations before you make an investment decision. 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.
