To start with, the typical Ibank "trader" is actually working in tandem with the "salesman," and he is not "trading" so much as exploiting relationships. The client is the mark, the salesman is the smooth talker who lures the client into danger, and the desk trader is the predator who either nips him- takes a little chunk out of his hind quarters- or else rips him- takes him for all he is worth, rips his lungs out. The Ibank "trading" game is more about working clients than it is actual discretionary trading. They smooth talk their way into deals and take crumbs off the cake, or they take the other side of blowup trades where the client gets fragged and the ibank was on the other side cashing in the chips. This is why most desk traders at ibanks are sharks with no morals; you have to be a shark to survive and thrive in that environment.
I would love to see an in-depth study of trading desk profitability at the major institutions. Of course, we will never see such a study because the big boys would not air their dirty laundry. But I would bet my last dollar that 80% of those guys' profitability comes from the relationships they have exploited and the clients they have screwed, rather than true trading prowess of any kind. Furthermore, when they DO try genuine directional trading, those desks have a consistently nasty habit of blowing up. The typical routine is for some overly aggressive idiot to make fifty million for the firm over a few years of favorable conditions, and then lose two hundred million in less than 24 hours when the laws of probability finally catch up with him. For every Nick Leeson or Sumitomo or LTCM or John Rusnak you hear about, there are another ten or twenty more fallen heroes that fragged their employers but weren't big enough to make the news.
Currency traders at the big banks have the same deal: most of their profits come from exploiting relationships and taking the other side of customer trades. If anything, their "trader" operations aside from taking bid/ask nips probably has a net negative effect on p&l....but the traders have to have something to do so they don't feel like trained monkeys.
I'm not saying there are no genuine successful traders in the institutions...there are a few, but they are probably only one out of ten, just like elsewhere, and they are not stupid enough to think they are bigger than the market. Show me a blowhard and I'll show you someone bound to take himself down sooner or later. Common sense observation supports the notion that while ego and self centered cruelty are assets when it comes to exploitation, they are liabilities when it comes to true trading. Anything that prevents you from seeing things with 100% clarity is a negative for the trader, and being a prideful SOB falls under that category.
