I am not sure what the purpose of this thread is beside to carry on like pork-chops over what seems to me to be a normal ebb and flow associated with the SP.
Now I am sure that TobyJack and/or Prime will happily chirp in to educate us / comment as to what is happening, but it appears to me that UBS Group AG and its related bodies corporate has been quite active in the stock from their announcements.
5 December announced that they had become a substantial shareholder
23 December announced that they had ceased to become a substantial shareholder
2nd January announced that they had become a substantial shareholder
13 January announced that they had ceased to become a substantial shareholder
There seems to be a couple of others playing this game of becoming / ceasing / becoming / etc.
Is this any reason for the Chicken Little syndrome and hysteria that is occupying the thread? From the above, I think that it does not appear to be such a big deal, but I am sure that more active commentators that hold and do not hold the stock will have an opinion.
