You need to know enough about finance to be able to speak the language. I relate it to communication. If I am going to go to a foreign country if I know how to speak the language, I am going to have a much better trip than if I have no idea how to speak the language. That does not mean that I have to be a professional speaker or that I have to be a literary genius in that language. But, I have to have a basic level of literacy.
