yep, where one goes the other will follow....eventually.
The probelm is the ownership of Advent is so complicated, the average punter (im not talking about the people that post on HC, but casual investors) would just look at the respective stakes in Advent and figure that MMR is the best company to get exposure to the PEP11 permit.
I think that so long as MMR trades upward of 20c, buying GBA at these levels is a no brainer.
