Although some investors may jump to the conclusion that this is a great buying opportunity, understanding the assumptions behind the P/E ratio might change your mind. In this article, 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 Green Plains Partners

### What you need to know about the P/E ratio

A common ratio used for relative valuation is the P/E ratio. It compares a stock’s price per share to the stock’s earnings per share. A more intuitive way of understanding the P/E ratio is to think of it as how much investors are paying for each dollar of the company’s earnings.

Formula

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

P/E Calculation for GPP

Price per share = \$17.6

Earnings per share = \$1.764

∴ Price-Earnings Ratio = \$17.6 ÷ \$1.764 = 10x

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 preferably want to compare the stock’s P/E ratio to the average of companies that have similar features to GPP, such as capital structure and profitability. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. Since similar companies should technically have similar P/E ratios, we can very quickly come to some conclusions about the stock if the ratios differ.

At 10x, GPP’s P/E is lower than its industry peers (13.9x). This implies that investors are undervaluing each dollar of GPP’s earnings. Therefore, according to this analysis, GPP is an under-priced stock.

### A few caveats

Before you jump to the conclusion that GPP 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 GPP. If this isn’t the case, the difference in P/E could be due to some other factors. For example, if you are inadvertently comparing lower risk firms with GPP, then GPP’s P/E would naturally be lower than its peers, since investors would value those with lower risk with a higher price. The other possibility is if you were accidentally comparing higher growth firms with GPP. In this case, GPP’s P/E would be lower since investors would also reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing GPP to are fairly valued by the market. If this does not hold, there is a possibility that GPP’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 GPP 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.
