Should You Buy Rolls-Royce Holdings plc (LON:RR.) At This PE Ratio?

Blake Harford

Rolls-Royce Holdings plc (LSE:RR.) is trading with a trailing P/E of 3.8x, which is lower than the industry average of 20.8x. While this makes RR. appear like a great stock to buy, you might change your mind after I explain the assumptions behind the P/E ratio. 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. View our latest analysis for Rolls-Royce Holdings

Demystifying the P/E ratio

LSE:RR. PE PEG Gauge Apr 22nd 18

The P/E ratio is one of many ratios used in 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 pound of the company’s earnings.

P/E Calculation for RR.

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

RR. Price-Earnings Ratio = £8.66 ÷ £2.294 = 3.8x

On its own, the P/E ratio doesn’t tell you much; however, it becomes extremely useful 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 RR., 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 RR.’s P/E of 3.8x is lower than its industry peers (20.8x), it means that investors are paying less than they should for each dollar of RR.’s earnings. Therefore, according to this analysis, RR. is an under-priced stock.

Assumptions to be aware of

However, before you rush out to buy RR., it is important to note that this conclusion is based on two key assumptions. The first is that our “similar companies” are actually similar to RR., or else the difference in P/E might be a result of other factors. For example, if you are comparing lower risk firms with RR., 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 RR. to are fairly valued by the market. If this does not hold true, RR.’s lower P/E ratio may be because firms in our peer group are 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 undervaluation could signal a good buying opportunity to increase your exposure to RR.. 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.
