# Is Lennox International Inc (NYSE:LII) Attractive At Its Current PE Ratio?

This analysis is intended to introduce important early concepts to people who are starting to invest and want to learn about the link between company’s fundamentals and stock market performance.

Lennox International Inc (NYSE:LII) is currently trading at a trailing P/E of 29.1, which is higher than the industry average of 21.4. Though this might seem to be a negative, you might change your mind after I explain the assumptions behind the P/E ratio. Today, I will break down what the P/E ratio is, how to interpret it and what to watch out for.

### Demystifying the P/E ratio

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

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

LII Price-Earnings Ratio = \$227.59 ÷ \$7.824 = 29.1x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. We want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as LII, such as size and country of operation. A common peer group is companies that exist in the same industry, which is what I use. LII’s P/E of 29.1 is higher than its industry peers (21.4), which implies that each dollar of LII’s earnings is being overvalued by investors. This multiple is a median of profitable companies of 25 Building companies in US including Noda, Jewett-Cameron Trading and Masonite International. You could think of it like this: the market is pricing LII as if it is a stronger company than the average of its industry group.

### A few caveats

However, it is important to note that our examination of the stock is based on certain assumptions. The first is that our “similar companies” are actually similar to LII. If not, the difference in P/E might be a result of other factors. For example, if Lennox International Inc is growing faster than its peers, then it would deserve a higher P/E ratio. We should also be aware that the stocks we are comparing to LII may not be fairly valued. So while we can reasonably surmise that it is optimistically valued relative to a peer group, it might be fairly valued, if the peer group is undervalued.

### What this means for you:

Since you may have already conducted your due diligence on LII, the overvaluation of the stock may mean it is a good time to reduce your current holdings. But at the end of the day, keep in mind that relative valuation relies heavily on critical assumptions I’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.
