Banking Coverage Groups and Entrepreneurship

I've gotten the impression that many people entering banking ultimately want to be the founders of their own companies, or at least in some way go into business for themself. Setting aside the obvious point that banking, at least at the analyst/associate levels, isn't very good preparation for entrepreneurship...

What coverage groups would be best as preparation for entrepreneurship?

I assume tech would be good, since it finds its way into every new business. Consumer could be good (you get to see how consumers think).

All input is appreciated.
