If you are thinking of hedge fund, investment banking, the math, econ, finance quan majors are idea as previously mentioned. It better to graduate from a top 10 and possibly top 15 undergrauate school. Beyond 15, it gets dicey. For example, when recruiting undergrads, firms such as Goldman Sachs, Chase, etc, generally recruit from the top 10 undergraduate business schools. or top peer schools in math/economics, etc.
