So it's a whale that is buying you say. Well then, who is the whale that has these amounts to sell? Seems like some one either wants out bad or the company is releasing shares to them. Take your pick.
All well and good but you are not looking at the SELL side. It that is an extra large amount of buying or accumulation in a hurry it is also an extra large amount of selling. The SELLING is a fact. And who has a large volume of shares available to sell ? And why would they now be selling at the price bottom or close to it right now if this Company was any good ?
