I agree with the shorting, because MMs knew those with the divy shares that were tradeable, would immediately dump. That's a no brainer. Soon, they will have to cover...
when someone buys that counts against the volume and when they sell it counts against it so when they buy 30 million and then sell that 30 million to drive the price down that counts as 60 million on the volume it all depends on how many time your broker lets you buy and sell the same stock in one day scottrade lets me do it like 3 times.
