To me, it's funny about this profitability stuff being the engine of revenue. Make no mistake, there are 2 distinct sides of the business- the houe and the customer. The traders are the customers and the firms are the house. The house makes money always and the customers make money rarely if ever. This is the simple model that has existed on Wall St. since it's beginnings. You are either on the inside or you are on the outside. And if you can't figure out which side you are on, you are on the outside. Who do you think is richer and has a more steady income stream, Goldman Sachs, Morgan Stanley, Generic Trading, (insert any name you like), or it's customers? Simple answer to that one. A model based on the profits of it's customers will not work simply because they will generally have no profits. Some may say i'm cynical. I say that I am either more experienced or the only truly honest person to say such things. Find an real 'edge' like the house has or be relegated to being a gambler at the casino like 99% of all players in this market. The few make money from the many (and they make good money at that!). In case you didn't know, Wall St. has produced more millionaires and super-millionaires (100x more than professional sports) than any other career in this world (as an insider of course). There are guys that most would never recognize their names from Adam that make A-Rod's salary look like chicken feed. Welcome all comers....Neal.
