# Does Bank Polska Kasa Opieki SA.’s (WSE:PEO) PE Ratio Warrant A Buy?

Bank Polska Kasa Opieki SA. (WSE:PEO) is currently trading at a trailing P/E of 13.1x, which is lower than the industry average of 16.4x. While this makes PEO appear like a great stock to buy, you might change your mind after I explain the assumptions behind the P/E ratio. Today, I will break down what the P/E ratio is, how to interpret it and what to watch out for. See our latest analysis for Bank Polska Kasa Opieki

### Breaking down the P/E ratio

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

Price per share = PLN123.85

Earnings per share = PLN9.43

∴ Price-Earnings Ratio = PLN123.85 ÷ PLN9.43 = 13.1x

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 PEO, such as company lifetime and products sold. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. Since it is expected that similar companies have similar P/E ratios, we can come to some conclusions about the stock if the ratios are different.

At 13.1x, PEO’s P/E is lower than its industry peers (16.4x). This implies that investors are undervaluing each dollar of PEO’s earnings. As such, our analysis shows that PEO represents an under-priced stock.

### A few caveats

Before you jump to the conclusion that PEO represents the perfect buying opportunity, it is important to realise that our conclusion rests on two important assertions. The first is that our peer group actually contains companies that are similar to PEO. If this isn’t the case, the difference in P/E could be due to some other factors. For example, if you are inadvertently comparing lower risk firms with PEO, then PEO’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 PEO. In this case, PEO’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 PEO to are fairly valued by the market. If this does not hold, there is a possibility that PEO’s P/E is lower because firms in our peer group are being overvalued by the market.

### 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 PEO 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.
