# Should You Be Tempted To Sell Sonel SA (WSE:SON) At Its Current PE Ratio?

This analysis is intended to introduce important early concepts to people who are starting to invest and want to start learning about core concepts of fundamental analysis on practical examples from todayâ€™s market.

Sonel SA (WSE:SON) trades with a trailing P/E of 17x, which is higher than the industry average of 7.7x. While SON might seem like a stock to avoid or sell if you own it, it is important to understand the assumptions behind the P/E ratio before you make any investment decisions. Today, I will break down what the P/E ratio is, how to interpret it and what to watch out for.

### Breaking down the Price-Earnings ratio

The P/E ratio is one of many ratios used in relative valuation. By comparing a stockâ€™s price per share to its earnings per share, we are able to see how much investors are paying for each dollar of the companyâ€™s earnings.

P/E Calculation for SON

Price-Earnings Ratio = Price per share Ã· Earnings per share

SON Price-Earnings Ratio = PLN6.16 Ã· PLN0.362 = 17x

The P/E ratio itself doesnâ€™t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. We want to compare the stockâ€™s P/E ratio to the average of companies that have similar characteristics as SON, such as size and country of operation. One way of gathering a peer group is to use firms in the same industry, which is what Iâ€™ll do. At 17x, SONâ€™s P/E is higher than its industry peers (7.7x). This implies that investors are overvaluing each dollar of SONâ€™s earnings. This multiple is a median of profitable companies of 9 Electronic companies in PL including ASBISc Enterprises, AB and Eurotel. As such, our analysis shows that SON represents an over-priced stock.

### Assumptions to be aware of

However, before you rush out to sell your SON shares, it is important to note that this conclusion is based on two key assumptions. Firstly, our peer group contains companies that are similar to SON. If this isnâ€™t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with SON, 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 SON to are fairly valued by the market. If this is violated, SONâ€™s P/E may be lower than its peers as they are actually overvalued by investors.

### What this means for you:

Since you may have already conducted your due diligence on SON, the overvaluation of the stock may mean it is a good time to reduce your current holdings. But at the end of the day, keep in mind that relative valuation relies heavily on critical assumptions Iâ€™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.
