# What Does GrainCorp Limited’s (ASX:GNC) PE Ratio Tell You?

This article is intended for those of you who are at the beginning of your investing journey and want to begin learning about how to value company based on its current earnings and what are the drawbacks of this method.

GrainCorp Limited (ASX:GNC) is currently trading at a trailing P/E of 25.6, which is higher than the industry average of 19. While this might not seem positive, it is important to understand the assumptions behind the P/E ratio before you make any investment decisions. Today, I will break down what the P/E ratio is, how to interpret it and what to watch out for.

### Breaking down the Price-Earnings 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.

P/E Calculation for GNC

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

GNC Price-Earnings Ratio = A\$8 ÷ A\$0.312 = 25.6x

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 GNC, 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 GNC’s P/E of 25.6 is higher than its industry peers (19), it means that investors are paying more for each dollar of GNC’s earnings. This multiple is a median of profitable companies of 20 Food companies in AU including Jiajiafu Modern Agriculture, Bojun Agriculture Holdings and Dongfang Modern Agriculture Holding Group. You could also say that the market is suggesting that GNC is a stronger business than the average comparable company.

### Assumptions to watch out for

However, you should be aware that this analysis makes certain assumptions. Firstly, that our peer group contains companies that are similar to GNC. If this isn’t the case, the difference in P/E could be due to other factors. For example, if GrainCorp Limited is growing faster than its peers, then it would deserve a higher P/E ratio. We should also be aware that the stocks we are comparing to GNC may not be fairly valued. So while we can reasonably surmise that it is optimistically valued relative to a peer group, it might be fairly valued, if the peer group is undervalued.

### What this means for you:

Since you may have already conducted your due diligence on GNC, the overvaluation of the stock may mean it is a good time to reduce your current holdings. But at the end of the day, keep in mind that relative valuation relies heavily on critical assumptions I’ve outlined 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.
