# Should You Be Tempted To Sell Electrocomponents plc (LON:ECM) At Its Current PE Ratio?

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 learn about the link between companyâ€™s fundamentals and stock market performance.

Electrocomponents plc (LON:ECM) is trading with a trailing P/E of 21.5, which is higher than the industry average of 18. Although some investors may see this as unappealing, it is important to understand the assumptions behind the P/E ratio before making judgments. In this article, I will explain what the P/E ratio is as well as what you should look out for when using it.

### Breaking down the Price-Earnings ratio

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

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

ECM Price-Earnings Ratio = Â£7.3 Ã· Â£0.339 = 21.5x

The P/E ratio isnâ€™t a metric you view in isolation and only becomes useful when you compare it against other similar companies. Our goal is to compare the stockâ€™s P/E ratio to the average of companies that have similar attributes to ECM, such as company lifetime and products sold. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. Since ECMâ€™s P/E of 21.5 is higher than its industry peers (18), it means that investors are paying more for each dollar of ECMâ€™s earnings. This multiple is a median of profitable companies of 22 Electronic companies in GB including UniVision Engineering, Spectris and Image Scan Holdings. You could also say that the market is suggesting that ECM is a stronger business than the average comparable company.

### Assumptions to be aware of

Before you jump to conclusions it is important to realise that there are assumptions in this analysis. Firstly, that our peer group contains companies that are similar to ECM. If this isnâ€™t the case, the difference in P/E could be due to other factors. Take, for example, the scenario where Electrocomponents plc is growing profits more quickly than the average comparable company. In that case, the market may be correct to value it on a higher P/E ratio. We should also be aware that the stocks we are comparing to ECM may not be 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:

If your personal research into the stock confirms what the P/E ratio is telling you, it might be a good time to rebalance your portfolio and reduce your holdings in ECM. 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.
