Breaking down the Price-Earnings ratio

ASX:TPM PE PEG Gauge Apr 19th 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.


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

P/E Calculation for TPM

Price per share = A$5.25

Earnings per share = A$0.43

∴ Price-Earnings Ratio = A$5.25 ÷ A$0.43 = 12.2x

The P/E ratio isn’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 stock’s P/E ratio to the average of companies that have similar features to TPM, such as capital structure and profitability. 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.

TPM’s P/E of 12.2x is lower than its industry peers (20.7x), which implies that each dollar of TPM’s earnings is being undervalued by investors. Therefore, according to this analysis, TPM is an under-priced stock.

Assumptions to be aware of

Before you jump to the conclusion that TPM represents the perfect buying opportunity, it is important to realise that our conclusion rests on two important assertions. The first is that our peer group actually contains companies that are similar to TPM. If this isn’t the case, the difference in P/E could be due to some other factors. For example, if you accidentally compared higher growth firms with TPM, then TPM’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 TPM, TPM’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 TPM to are fairly valued by the market. If this assumption is violated, TPM’s P/E may be lower than its peers because its peers are actually overvalued by investors.
