What pair do you guy trade and why?
OK, if momentum traders make money it means stat arb traders lose. Someone has got to lose. But they do not admit it. Momentum is the name of the game now. Use the sense you got.
This is not true. A win of a monentum user just means a lose for another momentum user bid on another side.
All momentum traders use the same simple models.
I never see investment bank hires people only know simple models to trade or create strategies, math/physics phd is like basic requirement.
Because you do not know what they do. Investment banks create financial products and the math is needed for pricing/hedging/arbitrage. Funds trade systems and in most cases the algos are as simple as a moving average crossover.
So what is this? Disneyland imagination story?

As the previous poster mentioned, your link describes an IB creating a financial product - namely, they are monetizing their relationships with top traders who go out start up their own funds. Furthermore, there is no mention that per your premise in your original post these traders were stat arb types.
I just want to point out there are serious traders in FI and their algos are NOT "as simple as a moving average crossover."
Point taken. In return, I just wanted to point out that the stat arb space has been crowded to the hilt for years now - and given the ECN and computing infrastructure requirements ($$$$$) stat arb is probably not a reasonable endeavor for the vast majority of individual speculators and ET Member types. Just my two cents.
