# Should You Buy Dunkin’ Brands Group Inc (NASDAQ:DNKN) At This PE Ratio?

Dunkin’ Brands Group Inc (NASDAQ:DNKN) trades with a trailing P/E of 15.8x, which is lower than the industry average of 21.7x. While this makes DNKN 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 deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio. Check out our latest analysis for Dunkin’ Brands Group

### Breaking down the P/E ratio

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 DNKN

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

DNKN Price-Earnings Ratio = \$60.92 ÷ \$3.862 = 15.8x

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 want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as DNKN, 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. DNKN’s P/E of 15.8x is lower than its industry peers (21.7x), which implies that each dollar of DNKN’s earnings is being undervalued by investors. As such, our analysis shows that DNKN represents an under-priced stock.

### Assumptions to watch out for

While our conclusion might prompt you to buy DNKN immediately, there are two important assumptions you should be aware of. Firstly, our peer group contains companies that are similar to DNKN. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you compared higher growth firms with DNKN, then its P/E would naturally be lower since investors would reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing DNKN to are fairly valued by the market. If this does not hold, there is a possibility that DNKN’s P/E is lower because our peer group is 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 DNKN. 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.
