Profunds index and sector trading

[otraque]

I have been reading a deep study of market changes and one of these changes is massive proliferation of hedge funds.
The buy only, no thinking just buy, computerized program buyers have a now very sizable group that think, this is not good for the NEVER bearish--never ever bearish.
They have been building short positions against their long positions this sets up the potential for a train wreck for the don't think just buy.
The Big Boys are essentially the major major BIG hedge funds, Big Boys play both sides, Big Boys are ruthless.
If they build a short position that is getting overly loaded as the buy programming twits just keeps propping the market they will go to sell longs /sell longs, creating a selling pressure the program buyers can not keep up with.
The much altered market place has developed a formulation now that theoritically has CRASH potential.
Just something to keep in mind.
