There's nothing at all that any regulator can do in the market that would interfere/restrict/encourage the way investors choose to accept or hedge any risks.  It would be like trying to make a marathon fairer by requiring faster runners to carry weights.  Next, you'd be giving slower runners motor assists of varying horsepower. In the end, what you'd have is a laughable mess that proves nothing. The market has never had the information age assist of group work to contend with, but "truth" will eventually arrive when some of these players find that they cannot get out when the time comes, or cover when the need arises.  Eventually, the market pitfalls will eviscerate these group players, bringing these games to an end.
