This post is another in a series I plan do on an irregular basis. A “quickie” idea is an investment specific idea that I’ve been mulling over and find interesting, but haven’t dove fully into yet. The hope with this particular idea is to provide the jumping off point for a discussion of an idea I find extremely interesting right now, as I suspect the opportunity could be fleeting but it’s liquid enough that just about anyone could participate at any size. The idea? Buying Navistar (NAV).
