# Should You Be Tempted To Buy Tyson Foods Inc (NYSE:TSN) Because Of Its PE Ratio?

The content of this article will benefit those of you who are starting to educate yourself about investing in the stock market and want to start learning about core concepts of fundamental analysis on practical examples from today’s market.

Tyson Foods Inc (NYSE:TSN) is trading with a trailing P/E of 7.7, which is lower than the industry average of 17.8. While this makes TSN appear like a good stock to buy, you might change your mind after I explain the assumptions behind the P/E ratio. In this article, I will deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio.

### Breaking down the Price-Earnings ratio

P/E is a popular ratio used for relative valuation. 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 TSN

Price per share = \$60.29

Earnings per share = \$7.872

∴ Price-Earnings Ratio = \$60.29 ÷ \$7.872 = 7.7x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. Ideally, we want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as TSN, such as size and country of operation. A quick method of creating a peer group is to use companies in the same industry, which is what I will 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.

TSN’s P/E of 7.7 is lower than its industry peers (17.8), which implies that each dollar of TSN’s earnings is being undervalued by investors. This multiple is a median of profitable companies of 24 Food companies in US including China Modern Agricultural Information, Amira Nature Foods and Hostess Brands. You can think of it like this: the market is suggesting that TSN is a weaker business than the average comparable company.

### Assumptions to be aware of

However, it is important to note that this conclusion is based on two key assumptions. The first is that our “similar companies” are actually similar to TSN. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you are inadvertently comparing lower risk firms with TSN, then TSN’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 TSN. In this case, TSN’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 TSN to are fairly valued by the market. If this does not hold, there is a possibility that TSN’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 TSN 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.
