I don't think the Moby/5% ann today had an impact. I would summise that the drop from 43 to 42c was profit taking after yesterday's rise.
I think you have seen most of the T+3 traders (or insiders) sell out already, so if it was going sub 40c it should have done it by now.
What I think we are going to see now is the likes of ahpigsy who sold out expecting a significant drop, buying back in at 42c+ to avoid missing the next rises and after waiting so long. I have said before that I think this is headed to 60c+ pre-drill without any new news. The last bit is important because MEO are now cashed up so may now have a few moves of their own or are a lucrative target.
