Its a fact that since 2007 volume of shares traded has dropped dramatically and the money has flowed into options. Options are now the dog and stocks the tail? just a thought.
It is both. It is staying neutral, but they are also looking to profit from the hedges, options trading.
who thinks it`s it`s manipulation
and who thinks it`s result of institutional delta neutral positioning that just looks like manipulation?
It is actually both. They manipulate the price by selling to themselves and balancing the books at the end of the day. It happens too frequently for it to not be controlled.
