I guess that the possibility that creditors/insiders are dumping shares is not to be considered huh? It's always speculated that some fantastic news or mysterious accumulation is happening is the real reason, and invariably eventually the facts or disclosures point to a dump, IMO
EDIT: Dog, CFG; ck the individual trades and see if you see swapping going on. If you analyze even the non-matching numbers you can reasonably assume that it's mostly swapping going on possibly to project an imaginary demand and stimulate the unknowing to partake.
