Success in trading not quite related to school level, imo.
Lol, remember the bunch phd's and mathematicians/engineers at LTCM ? They almost kaputted the markets with all those diplomas.
Actually it is, education level teaches you patience hence why Harvard, Cambridge have higher success rates with high income levels. Patience is also a prerequisite to trade the markets, however, anyone can synthetically adjust their lifestyle to force patience and over a decade or two it will convert in to natural patience, but that is rare.
The problem with LTCM is that they were technical focused and forgot one small point, human nature breaks technicals at the most inopportune time, usually when you are over-leveraged. The PHDs were required to sell the models to the investment community.
