Rusty, I don't follow your logic regarding Alkane selling. Why would they sell while accumulating, especially if, as is likely, the combined effect of buying and selling x shares leaves the price unchanged. All they achieve is to line the broker's pockets.
The pattern of their buying looks like spare cash buying. Nonetheless, it possibly telegraphs a continuing interest in accumulation that might result in the cash earmarked for the abandoned purchase coming Calidus' way.
I wonder what is in DR's mind as up to now he has seemed to want Calidus independent. Perhaps it is a clever way of gaining funding.
