# Does Pizza Pizza Royalty Corp’s (TSX:PZA) PE Ratio Warrant A Buy?

Pizza Pizza Royalty Corp (TSX:PZA) is trading with a trailing P/E of 19.2x, which is lower than the industry average of 24.9x. While PZA might seem like an attractive stock to buy, it is important to understand the assumptions behind the P/E ratio before you make any investment decisions. Today, I will deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio. See our latest analysis for PZA

### What you need to know about the P/E ratio

The P/E ratio is a popular ratio used in relative valuation since earnings power is a key driver of investment value. 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 PZA

Price per share = 16.75

Earnings per share = 0.87

∴ Price-Earnings Ratio = 16.75 ÷ 0.87 = 19.2x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. Ultimately, our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to PZA, such as company lifetime and products sold. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. Since similar companies should technically have similar P/E ratios, we can very quickly come to some conclusions about the stock if the ratios differ.

At 19.2x, PZA’s P/E is lower than its industry peers (24.9x). This implies that investors are undervaluing each dollar of PZA’s earnings. As such, our analysis shows that PZA represents an under-priced stock.

### Assumptions to watch out for

However, before you rush out to buy PZA, it is important to note that this conclusion is based on two key assumptions. The first is that our peer group actually contains companies that are similar to PZA. 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 PZA, then PZA’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 PZA, PZA’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 PZA to are fairly valued by the market. If this assumption is violated, PZA's P/E may be lower than its peers because its peers are actually overvalued by investors.

### What this means for you:

Are you a shareholder? 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 PZA. 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.

Are you a potential investor? If PZA has been on your watch list for a while, it is best you also consider its intrinsic valuation. Looking at PE on its own will not give you the full picture of the stock as an investment, so I suggest you should also look at other relative valuation metrics like EV/EBITDA or PEG.

PE is one aspect of your portfolio construction to consider when holding or entering into a stock. But it is certainly not the only factor.
