# Should You Be Tempted To Buy Tate & Lyle plc (LON:TATE) At Its Current PE Ratio?

This article is intended for those of you who are at the beginning of your investing journey and want to start learning about core concepts of fundamental analysis on practical examples from todayâ€™s market.

Tate & Lyle plc (LON:TATE) is trading with a trailing P/E of 11.1x, which is lower than the industry average of 22.6x. While this makes TATE appear like a great stock to buy, you might change your mind after I explain the assumptions behind the P/E ratio. In this article, I will explain what the P/E ratio is as well as what you should look out for when using it.

### Demystifying the P/E ratio

P/E is a popular ratio used for relative valuation. By comparing a stockâ€™s price per share to its earnings per share, we are able to see how much investors are paying for each dollar of the companyâ€™s earnings.

P/E Calculation for TATE

Price-Earnings Ratio = Price per share Ã· Earnings per share

TATE Price-Earnings Ratio = Â£6.33 Ã· Â£0.569 = 11.1x

The P/E ratio isnâ€™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 stockâ€™s P/E ratio to the average of companies that have similar features to TATE, such as capital structure and profitability. One way of gathering a peer group is to use firms in the same industry, which is what Iâ€™ll do. Since TATEâ€™s P/E of 11.1 is lower than its industry peers (22.6), it means that investors are paying less for each dollar of TATEâ€™s earnings. This multiple is a median of profitable companies of 17 Food companies in GB including Dairy Crest Group, Anglo-Eastern Plantations and Wynnstay Group. You can think of it like this: the market is suggesting that TATE is a weaker business than the average comparable company.

### A few caveats

However, there are two important assumptions you should be aware of. Firstly, our peer group contains companies that are similar to TATE. If this isnâ€™t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with TATE, then its P/E would naturally be lower than its peers, as investors would value those with lower risk at a higher price. The second assumption that must hold true is that the stocks we are comparing TATE to are fairly valued by the market. If this does not hold true, TATEâ€™s lower P/E ratio may be because firms in our peer group are overvalued by the market.

### What this means for you:

You may have already conducted fundamental analysis on the stock as a shareholder, so its current undervaluation could signal a good buying opportunity to increase your exposure to TATE. Now that you understand the ins and outs of the PE metric, you should know to bear in mind its limitations before you make an investment decision. 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.
