Does Tonkens Agrar AG’s (FRA:GTK) PE Ratio Warrant A Buy?

Tonkens Agrar AG (DB:GTK) is currently trading at a trailing P/E of 7.8x, which is lower than the industry average of 18.1x. 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. Today, I will break down what the P/E ratio is, how to interpret it and what to watch out for. Check out our latest analysis for Tonkens Agrar

What you need to know about the P/E ratio

The P/E ratio is a popular ratio used in relative valuation since earnings power is a key driver of investment value. 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 dollar of the company’s earnings.

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. Ultimately, our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to GTK, 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. 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 7.8x, GTK’s P/E is lower than its industry peers (18.1x). This implies that investors are undervaluing each dollar of GTK’s earnings. Therefore, according to this analysis, GTK is an under-priced stock.

Assumptions to watch out for

While our conclusion might prompt you to buy GTK immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to GTK. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you accidentally compared higher growth firms with GTK, then GTK’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 GTK, GTK’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 GTK to are fairly valued by the market. If this assumption is violated, GTK’s P/E may be lower than its peers because its peers are actually overvalued by investors.

What this means for you:

Since you may have already conducted your due diligence on GTK, the undervaluation of the stock may mean it is a good time to top up on 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.
