I want to start a carrer in the stock market, gradually do my MBA and then start a business and probably an investment firm myself. What will be the best way to go about doing this ? Are there any courses i will have to undergo so that i can get into any broking/ investment firm ?
This really depends on were you are in life. If you're 7 years old, then the path would be different than if you're 70. Presuming you're in undergrad, the easiest path would be to pursue a finance/economics major (Depending on your degree options). Attempt to study for, take, and pass the CFA 1 as a Junior and the CFA 2 as a Senior. There are scholarships available for undergrads taking the CFA. Presuming you pass the first two parts, you shouldn't have any trouble landing, preparing for, and acing an interview with Goldman Sachs. You can pass part 3 during your first or second year at GS. Spend a couple of years with them in banking, then apply to Harvard Business School. Graduate from school, get a job with a hedge fund or large investment firm, spend a few years learning how to consistently outperform the market, and hopefully you can convince someone to invest $10mn in your new fund.
This sounds trite and slightly cynical, but it's a pretty proven path.
