My guess is that this is being fuelled by UBS, having picked up ~ 11M shares as a result of their part as joint UW for the RI. The upside of this is that the stock after a very decent run is forming a support base around this level; for the next leg up. Q report will be released no later than 29/01. IMO there is further upside to come; others surely think so considering the BOT action on the buy side. A little bit of patience is required.
