Why these three car stocks in particular? Well consider that two of the three, Copart and Carvana, operate largely online and are therefore largely insulated from the risk of both coronavirus contagion and being shuttered by government shutdown orders designed to slow the spread of the virus. CarMax, too, has a substantial internet-based sales operation. And even its physical stores may well be exempt from bans on the operation of "nonessential" businesses -- inasmuch as they facilitate an essential transportation service.
