Listed as Ordinary trades and probably dumping in advance of the new tranche of 150M shares @ 1p expected to be listed on 9th Jan - see last RNS. MMs probably didn't move the price 'cos they'd reckon on it being lower in a coupla weeks anyway, plus the lot they just soaked up can currently be sold on for 50% profit so therefore they'd not be doing themselves any favours by reducing the offer right now - might get themselves a little extra cash for Xmas.
No idea if there'll be anything else reported after the EGM on 3rd Jan but it would be nice to get an update on the Rio Tinto situation - they'll probably save that for results day later in Jan.
One thing though for sure is that Rio has featured strongly in the past coupla days in market news as being one of the buoyant stocks and being upgraded, so ANY positive news on RVD's tie-up with them should (IMO) have heads turning this way.
