They tell you to look for the beneficiary of an act to figure out who is most likely responsible for that act.
Over the last week or so, since the rumors began, brokerages made money on increased volume, traders made money in both directions on much increased volume and if there were some needing to get out of their SODA long positions without taking a real bath, well they did well also.
In a couple weeks, IMO, most likely we go back to much lower volume and the trading range of $38 -$41 because nothing has actually changed.
I don't think there is anything to the rumors at all except for the needs of some closer to mms and insiders to get out of their positions. I'll be glad to be wrong on this, but I doubt it.
