# Should You Be Tempted To Buy NewMarket Corporation (NYSE:NEU) Because Of Its PE Ratio?

NewMarket Corporation (NYSE:NEU) trades with a trailing P/E of 20x, which is lower than the industry average of 21.2x. While NEU 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. 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. View our latest analysis for NewMarket

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

P/E is a popular ratio used for relative valuation. 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 NEU

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

NEU Price-Earnings Ratio = \$392.53 Ã· \$19.587 = 20x

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 NEU, such as capital structure and profitability. A common peer group is companies that exist in the same industry, which is what I use. NEUâ€™s P/E of 20x is lower than its industry peers (21.2x), which implies that each dollar of NEUâ€™s earnings is being undervalued by investors. As such, our analysis shows that NEU represents an under-priced stock.

### Assumptions to watch out for

Before you jump to the conclusion that NEU 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 NEU. If this isnâ€™t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with NEU, then its P/E would naturally be lower than its peers, as investors would value those with lower risk at a higher price. The second assumption that must hold true is that the stocks we are comparing NEU to are fairly valued by the market. If this does not hold true, NEUâ€™s lower P/E ratio may be because firms in our peer group are overvalued by the market.
