Because there are some real differences between these two and their cohort.
I will have more later but when I read over CarMax what I think of is that it's used cars that are moving the stock up -- 2.1% growth versus an expectation of 0.98%. New cars, as we know from the weaker numbers from AutoNation (AN) , just aren't selling as well.
KB Home? Higher price points are selling out in California and gross margins are moving up smartly. The rest of the industry? It's good but no one cares. In fact, there was a moment on the KB Home call where management wanted to know what's the deal with Wall Street and why it thinks the cycle has peaked when there is such demand? It's not an easy conundrum to explain.
Maybe it is more case by case? I think it's a lesson that we mustn't group all stocks together and how these stocks are NOT representative. They our outliers and if anything, they enforce the notion that car sales are not strong and most housing sales just aren't enough to move the group higher.
