# Should You Be Tempted To Buy The Allstate Corporation (NYSE:ALL) Because Of Its PE Ratio?

The Allstate Corporation (NYSE:ALL) is currently trading at a trailing P/E of 10.1x, which is lower than the industry average of 14.4x. While this makes ALL 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 break down what the P/E ratio is, how to interpret it and what to watch out for. Check out our latest analysis for Allstate

### Breaking down 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 stockâ€™s price per share to the stockâ€™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 companyâ€™s earnings.

P/E Calculation for ALL

Price-Earnings Ratio = Price per share Ã· Earnings per share

ALL Price-Earnings Ratio = \$94.25 Ã· \$9.337 = 10.1x

The P/E ratio itself doesnâ€™t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. We preferably want to compare the stockâ€™s P/E ratio to the average of companies that have similar features to ALL, such as capital structure and profitability. One way of gathering a peer group is to use firms in the same industry, which is what Iâ€™ll do. At 10.1x, ALLâ€™s P/E is lower than its industry peers (14.4x). This implies that investors are undervaluing each dollar of ALLâ€™s earnings. As such, our analysis shows that ALL represents an under-priced stock.

### Assumptions to watch out for

Before you jump to the conclusion that ALL is the perfect buying opportunity, it is important to realise that our conclusion rests on two assertions. Firstly, our peer group contains companies that are similar to ALL. If this isnâ€™t the case, the difference in P/E could be due to other factors. For example, if you compared higher growth firms with ALL, then its P/E would naturally be lower since investors would reward its peersâ€™ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing ALL to are fairly valued by the market. If this does not hold, there is a possibility that ALLâ€™s P/E is lower because our peer group is overvalued by the market.

### What this means for you:

Since you may have already conducted your due diligence on ALL, the undervaluation of the stock may mean it is a good time to top up on your current holdings. But at the end of the day, keep in mind that relative valuation relies heavily on critical assumptions Iâ€™ve outlined 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.
