The career progression of a research analyst is associate->research analyst, where one stays while getting promoted to MD, if you are really good & in command of your sector (For simplicity, forget the Jack Grubmans of the world for now). For I-Bankers, becoming an MD is the goal, and if you can make some money on the way, that's even better. What about traders? One starts trading, let's say mortgage securities, and becomes an expert in trading MBS securities. What's next for you?
