commerce from Ivy League will get you into a solid investment bank that will give you the most room and resources to grow.don;t think commerce will make you automatically a good trader there is no degree that teaches you the skill set you need to be succesful in this industry that said it will probably certainly help.
Trading $500,000 or even a million by yourself is not enough to impress anyone.
