Have you ever noticed that when 10M to 20M shares trade hands ~ the share price hardly moves? In this last year, this phenomenon has happened many times with RFMD. Something balances all trades ~ and I think it could be Mazama's computer that does it...for what reason I don't know...!
I think that is institutional transfers. Not sure how off-market transfers show up, but that would explain it.
These are prearranged transfers, a way for institutions to shoft their portfolios without operating on the open market. It's become quite common, with institutions set up just to handle these transfers.
I think the 100M that was referred to is the same thing. Below $5 there would be many institutions who would want, or not want, the stock.
These penny stocks slowly shift into the hands of retail...
