Breaking down the Price-Earnings ratio

LSE:OML PE PEG Gauge Mar 14th 18
LSE:OML PE PEG Gauge Mar 14th 18

A common ratio used for relative valuation is the P/E ratio. 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 OML

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

OML Price-Earnings Ratio = £2.56 ÷ £0.156 = 16.4x

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. Our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to OML, 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. OML’s P/E of 16.4x is higher than its industry peers (15x), which implies that each dollar of OML’s earnings is being overvalued by investors. Therefore, according to this analysis, OML is an over-priced stock.

A few caveats

However, before you rush out to sell your OML 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 OML. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with OML, 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 OML to are fairly valued by the market. If this does not hold true, OML’s lower P/E ratio may be because firms in our peer group are overvalued by the market.
