Hello again, Adam,
I believe that an MBA is the surest way to learn about how businesses operate. With that understanding your analysis becomes richer and more complete because you start to think like the companies you are trying to understand. The other benefit of an MBA as taught in most programs is that you work in teams and this teaches many of the interpersonal skills necessary to succeed in the business world. These are skills not taught in the CFA program.
Also, if you attain your MBA (or another Masters in another field) no one can ever take that credential away from you. It is a permanent part of your package. To me that has tremendous appeal.
I consider an MBA and a CFA to be highly complementary of one another.
Go Adam, go!
Jason
