2 big ways:
1. Finance degree & MBA & CFA - then join a sell side research shop or investment banking firm as an analyst
2. Marketing degree ( or mabey finance as well but this isn't as common) - then MBA, then join market research firm such as EEDAR or whatever.
Market research salaries won't be as high as sell side research but you will have the benefit of being more objective rather than somebody who has to constantly overhype gaming companies so that their traders can move the stocks------- MS's Natal is going to be daaa shiznit, so buy now!!! buy buy buy. If you get your MBA though, you should be able to make 70K if you were an average, not poor employee, and not the highest one either. 120-150K including bonus would be the norm for somebody w/ an MBA and CFA as a sell side analyst
In either case you have to be mothodical, analytical, intellectually curious, etc. You'll also have to be a good writer because executives will be judging your reasoning partly by your writing skills, so if you arent a finance or marketing major and then get your MBA, then it would probably be a good idea to be something like an english or philosophy, mabey even history major. The degree of education will be immense so this isn't the kind of job that any troll on this board could hope to accomplish.
