I was wondering if somebody could please clarify the difference between Sales & Trading at a large brokerage house such as Merrill Lynch or Solomon and at a trading firm such as Bright, Echo, or Worldco. I am a young guy with a first-rate education and exceptional understanding of the market, having interned for a year at a Merrill Lynch retail office and in the education department at the NYSE, but I could never truly pinpoint this nuance. At a brokerage house, they will have you doing a lot of BS, such as making phone calls to clients, trying to sell people on various equities, correct? Kind of like Charlie Sheen in Wall St or Vin Diesel on the phone, selling people in Boiler Room. I just want a piece of the action, which will come with the Series 7 and 55, and am looking to do it as ethically as possible. Fully aware of the market's capacity to divide people into either winners or losers, somebody is to lose as a result of myself making money. I've read Liar's Poker, Reminiscences of a Stock Operator, and a number of other trading books, but any advice anybody on this board could give me would be greatly appreciated. Thanks!
