I know of at least 5 firms who would have the means to make a big profit in a rather stealth way and all of the infrastructure needed to minimize execution risk (to the point that it may be negligible)... Just because you cannot do it or that it is hard for you, do not assume it cannot be done or that it is (as) hard for everybody...
I do to, and all 5 of them make more money as part of the regular operation of the markets than they would as part of some Jerry Bruckheimer movie plot.
