Should You Be Tempted To Sell Spirax-Sarco Engineering plc (LON:SPX) At Its Current PE Ratio?

In this article:

I am writing today to help inform people who are new to the stock market and want to better understand how you can grow your money by investing in Spirax-Sarco Engineering plc (LON:SPX).

Spirax-Sarco Engineering plc (LON:SPX) is trading with a trailing P/E of 30.1x, which is higher than the industry average of 21.1x. While this makes SPX appear like a stock to avoid or sell if you own it, you might change your mind after I explain the assumptions behind the P/E ratio. In this article, I will break down what the P/E ratio is, how to interpret it and what to watch out for. View out our latest analysis for Spirax-Sarco Engineering

What you need to know about the P/E ratio

LSE:SPX PE PEG Gauge June 22nd 18

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.

P/E Calculation for SPX

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

SPX Price-Earnings Ratio = £64.6 ÷ £2.144 = 30.1x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. We want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as SPX, such as size and country of operation. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. Since SPX’s P/E of 30.1x is higher than its industry peers (21.1x), it means that investors are paying more than they should for each dollar of SPX’s earnings. As such, our analysis shows that SPX represents an over-priced stock.

Assumptions to be aware of

While our conclusion might prompt you to sell your SPX shares immediately, there are two important assumptions you should be aware of. Firstly, our peer group contains companies that are similar to SPX. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you compared lower risk firms with SPX, then investors would naturally value it at a lower price since it is a riskier investment. The second assumption that must hold true is that the stocks we are comparing SPX to are fairly valued by the market. If this does not hold, there is a possibility that SPX’s P/E is lower because our peer group is overvalued by the market.

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 SPX. 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.
