# Is TMX Group Limited’s (TSE:X) PE Ratio A Signal To Sell For Investors?

TMX Group Limited (TSX:X) is trading with a trailing P/E of 22.6x, which is higher than the industry average of 12.5x. While X might seem like a stock to avoid or sell if you own it, it is important to understand the assumptions behind the P/E ratio before you make any investment decisions. Today, I will explain what the P/E ratio is as well as what you should look out for when using it. See our latest analysis for TMX Group

### Demystifying the P/E ratio

P/E is often used for relative valuation since earnings power is a chief 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.

P/E Calculation for X

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

X Price-Earnings Ratio = CA\$86.4 ÷ CA\$3.824 = 22.6x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. Our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to X, such as company lifetime and products sold. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. At 22.6x, X’s P/E is higher than its industry peers (12.5x). This implies that investors are overvaluing each dollar of X’s earnings. Therefore, according to this analysis, X is an over-priced stock.

### A few caveats

Before you jump to the conclusion that X should be banished from your portfolio, it is important to realise that our conclusion rests on two assertions. Firstly, our peer group contains companies that are similar to X. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you compared lower risk firms with X, then investors would naturally value it at a lower price since it is a riskier investment. The second assumption that must hold true is that the stocks we are comparing X to are fairly valued by the market. If this is violated, X’s P/E may be lower than its peers as they are actually overvalued by investors.

### What this means for you:

You may have already conducted fundamental analysis on the stock as a shareholder, so its current overvaluation could signal a potential selling opportunity to reduce your exposure to X. 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.
