Is Ternium SA’s (NYSE:TX) PE Ratio A Signal To Buy For Investors?

Renee Allred

I am writing today to help inform people who are new to the stock market and want to begin learning the link between Ternium SA (NYSE:TX)’s fundamentals and stock market performance.

Ternium SA (NYSE:TX) is trading with a trailing P/E of 7x, which is lower than the industry average of 12.3x. 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 break down what the P/E ratio is, how to interpret it and what to watch out for. See our latest analysis for Ternium

Breaking down the Price-Earnings ratio

NYSE:TX PE PEG Gauge June 24th 18

A common ratio used for relative valuation is the P/E ratio. 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.

P/E Calculation for TX

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

TX Price-Earnings Ratio = $35.11 ÷ $5.051 = 7x

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 want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as TX, such as size and country of operation. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. TX’s P/E of 7x is lower than its industry peers (12.3x), which implies that each dollar of TX’s earnings is being undervalued by investors. As such, our analysis shows that TX represents an under-priced stock.

Assumptions to watch out for

While our conclusion might prompt you to buy TX immediately, there are two important assumptions you should be aware of. Firstly, our peer group contains companies that are similar to TX. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with TX, 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 TX to are fairly valued by the market. If this does not hold true, TX’s lower P/E ratio may be because firms in our peer group are 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 TX 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.
