CarMax stock reaction and insider activity after earnings

CarMax (KMX) drew attention after its latest earnings report initially triggered a sell-off. The stock then rebounded in June as analyst upgrades and insider buying, including purchases by the CEO and board members, supported sentiment.

At around $51.01, CarMax’s recent rebound has been strong, with a 30 day share price return of 6.25% and a year to date share price return of 29.83%, even though the 1 year total shareholder return is down 23.8%.

CarMax’s rebound and insider buying have bulls arguing the stock is resetting higher, while the weak 1 year return keeps bears focused on past pain. Which camp does the current valuation favor?

Most Popular Narrative: 1% Undervalued

CarMax is trading very close to the most widely followed fair value estimate of about $51.31, so the current price leaves little room for big valuation gaps.

CarMax's initiative to broaden its full credit spectrum lending capabilities through CarMax Auto Finance (CAF) is expected to increase CAF income and net interest margins over time. This initiative aims to capture more sales and improve financing income, impacting earnings positively.

Want to see what earnings profile sits behind that fair value line? The narrative leans on margin rebuild, flat revenue and a lower future earnings multiple than today.

Result: Fair Value of $51.31 (ABOUT RIGHT)

However, CarMax still faces pressure on wholesale gross profit per unit and rising competition for vehicle sourcing, which could squeeze margins if these headwinds persist.

Another view on CarMax using earnings multiples

The fair value narrative has CarMax looking roughly in line with analyst targets, but the current P/E of 32.1x tells a tougher story. It sits well above the US Specialty Retail industry at 19.6x, the peer average at 13.1x, and even the 24.7x fair ratio the market could drift toward over time. If earnings do not grow as expected, how much multiple compression risk are you really comfortable with?
