This article is written for those who want to get better at using price to earnings ratios (P/E ratios). We’ll look at CarMax, Inc.’s (NYSE:KMX) P/E ratio and reflect on what it tells us about the company’s share price. CarMax has a price to earnings ratio of 13.49, based on the last twelve months. In other words, at today’s prices, investors are paying $13.49 for every $1 in prior year profit.
How Do You Calculate A P/E Ratio?
The formula for P/E is:
Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)
Or for CarMax:
P/E of 13.49 = $58.78 ÷ $4.36 (Based on the year to November 2018.)
Is A High Price-to-Earnings Ratio Good?
A higher P/E ratio means that investors are paying a higher price for each $1 of company earnings. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.
How Growth Rates Impact P/E Ratios
P/E ratios primarily reflect market expectations around earnings growth rates. That’s because companies that grow earnings per share quickly will rapidly increase the ‘E’ in the equation. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.
CarMax increased earnings per share by an impressive 16% over the last twelve months. And its annual EPS growth rate over 5 years is 12%. With that performance, you might expect an above average P/E ratio.
How Does CarMax’s P/E Ratio Compare To Its Peers?
We can get an indication of market expectations by looking at the P/E ratio. If you look at the image below, you can see CarMax has a lower P/E than the average (15.6) in the specialty retail industry classification.
CarMax’s P/E tells us that market participants think it will not fare as well as its peers in the same industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.
A Limitation: P/E Ratios Ignore Debt and Cash In The Bank
It’s important to note that the P/E ratio considers the market capitalization, not the enterprise value. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.
Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.
How Does CarMax’s Debt Impact Its P/E Ratio?
CarMax’s net debt is considerable, at 138% of its market cap. If you want to compare its P/E ratio to other companies, you must keep in mind that these debt levels would usually warrant a relatively low P/E.
The Verdict On CarMax’s P/E Ratio
CarMax trades on a P/E ratio of 13.5, which is below the US market average of 16.7. While the EPS growth last year was strong, the significant debt levels reduce the number of options available to management. The low P/E ratio suggests current market expectations are muted, implying these levels of growth will not continue.
