What I have learned from both older daughters in their kind of multibillion dollar funds where they are employed that one need only simple math to do the investement analysis. However when a investors is investing in a single investment 10s of millions dollars, soft skills related to liberal arts skills are paramount as they take very long term view before investment is made. That has been drilled into kids head over and over again by their mentors who are very successful and these mentors are doing for a very very long time.
By the way both daughters took BC calc in early high school.
