mgo: a better value proposition than sfr, page-46

I've decided im buggered if I can figure this out. As far as i can tell someone big is selling, letting the buy side build up and then dump into it ?
Is anyone selling enough at 30 or 30.5 to sustain the volumes, besides a big investor ?
SP always seems to build up 0.5 or 1 cent and then drops back when a big chunk of shares gets traded ? Im open to all thoughts on this because the trading lately has been really strange. To me with all the positives to possibly come in the next couple of months, maybe sooner, why would you sell now ? I have a big holding in this and its starting to keep me up at night .... :-)
