i think there are two very important classifications of credentials --- since trading is purely a matter of quantifiable results, one of these classes does not matter --- that being how many letters you have next to your name or where they came from.
who would you rather take advice from or give props to--- a stock broker that drives a dodge neon, but might have an ivy league MBA ----or a stock trader who dropped out of a two year college, but has his series 3,4 and makes a 7 figure annual salary and drives a convertible ferrari?
i will choose the latter....its all about resluts in this business, nothing more....there is no room for fluff....in big companies, especially in marketing and business departments, a large emphasis is placed on pedigree degrees--- where did you go -- "i went to harvard, well i went to Oxford. great, these same brilliant people who took 1 whopping course in finance and might know what a call is, can not trade their way out of paper bag.
