Hi CEB2, what do think the UBS acquisition has had on the price pump we have seen since end December. The reason I ask is that, checking the top 20 holders in January UBS doesn't feature, at least not under this acronym. That suggests that UBS has acquired much of their 15% (around 300M shares) in the past 6 weeks. If this has been the major influence on the share price and responsible for much of the rise we have seen, what does it say about the volatility for the future when UBS stops buying - if they do? (realising that the expected announcements will no doubt continue to influence the SP but perhaps at a different level if they are not coincidental with a big buyer slamming into the sell side).

Hope this makes sense.
