# Is It Time To Buy Kopex SA. (WSE:KPX) Based Off Its PE Ratio?

Kopex SA. (WSE:KPX) is trading with a trailing P/E of 2.7x, which is lower than the industry average of 14.2x. While KPX 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. In this article, 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 Kopex

### What you need to know about the P/E ratio

P/E is a popular ratio used for relative valuation. 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.

Formula

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

P/E Calculation for KPX

Price per share = PLN2.43

Earnings per share = PLN0.91

∴ Price-Earnings Ratio = PLN2.43 ÷ PLN0.91 = 2.7x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful 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 KPX, such as capital structure and profitability. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. 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.

At 2.7x, KPX’s P/E is lower than its industry peers (14.2x). This implies that investors are undervaluing each dollar of KPX’s earnings. As such, our analysis shows that KPX represents an under-priced stock.

### Assumptions to be aware of

While our conclusion might prompt you to buy KPX immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to KPX. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you are inadvertently comparing lower risk firms with KPX, then KPX’s P/E would naturally be lower than its peers, since investors would value those with lower risk with a higher price. The other possibility is if you were accidentally comparing higher growth firms with KPX. In this case, KPX’s P/E would be lower since investors would also reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing KPX to are fairly valued by the market. If this does not hold, there is a possibility that KPX’s P/E is lower because firms in our peer group are being overvalued by the market.

### What this means for you:

Since you may have already conducted your due diligence on KPX, the undervaluation of the stock may mean it is a good time to top up on your current holdings. But at the end of the day, keep in mind that relative valuation relies heavily on critical assumptions I’ve outlined 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.
