Today, I will explain what the P/E ratio is as well as what you should look out for when using it. View our latest analysis for Plus500

### Breaking down the Price-Earnings ratio

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.

Formula

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

P/E Calculation for PLUS

Price per share = \$15.55

Earnings per share = \$1.745

∴ Price-Earnings Ratio = \$15.55 ÷ \$1.745 = 8.9x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. We preferably want to compare the stock’s P/E ratio to the average of companies that have similar features to PLUS, such as capital structure and profitability. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. Since it is expected that similar companies have similar P/E ratios, we can come to some conclusions about the stock if the ratios are different.

Since PLUS’s P/E of 8.9x is lower than its industry peers (14.2x), it means that investors are paying less than they should for each dollar of PLUS’s earnings. Therefore, according to this analysis, PLUS is an under-priced stock.

### A few caveats

Before you jump to the conclusion that PLUS represents the perfect buying opportunity, it is important to realise that our conclusion rests on two important assertions. The first is that our peer group actually contains companies that are similar to PLUS. If this isn’t the case, the difference in P/E could be due to some other factors. For example, if you accidentally compared higher growth firms with PLUS, then PLUS’s P/E would naturally be lower since investors would reward its peers’ higher growth with a higher price. Alternatively, if you inadvertently compared less risky firms with PLUS, PLUS’s P/E would again be lower since investors would reward its peers’ lower risk with a higher price as well. The second assumption that must hold true is that the stocks we are comparing PLUS to are fairly valued by the market. If this does not hold, there is a possibility that PLUS’s P/E is lower because firms in our peer group are being overvalued by the market.

### 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 add more of PLUS to your portfolio. 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.
