I have also thought about this after i graduate. I have heard it is an extremely stressful job. You are on commission pay and you wont make anything for a while until you build up clientele.
You need to get your Series 7 license. Its just like a stock broker job since you sell stocks too. Only problem with this job is that a lot of people dont last and end up quitting, its not for everyone...thats why the job is advertised all the time..some companies dont even require a degree or anything. Its a sales job.
But if you believe you can work on a commission and are good with numbers and people you should be successful. Just believe in yourself. The sky's the limit.
Its a great job if you want to learn how investing and money works.
