My thought is that you should major in finance rather than in math, if you wish to make a career in the financial industry. I too love math and majored in it in college. However, mathematics in itself doesn't carry a lot of weight when it comes to getting jobs. The statistics part is practical knowledge, yes, but the other parts of mathematics are mainly conceptual (abstract algebra, calculus, differential equations, etc.) Those have no bearing on a career in the finance industry.
I still love math, and study various topics as I run across them. It turned out that I took some accounting classes as electives, and somehow I wound up making good money doing accounting for several small businesses ~ even though I never got a degree or certification of any kind.
