Well I'm not sure what is evident and it's bugging the heck out of me.
My suspicious is that the buyers today are very carefully sniping away and any offers of sizeable lots of shares that come available. They sure aren't placing large bids and sitting there but coming into the market regularly with new bids. This is where, I suspect, the volume is coming from today. These guys are patient and CHEAP aiming to get as many shares as cheaply as they can.
Maybe news would put paid to this poaching or maybe it's a trend we have to live with. Or maybe I'm reading the action today completely wrong?
