Here's my take: On Thurs a bunch of new investors rushed in on huge volume and on Fri morning many of them took their profits. The huge volume Thurs afternoon and Fri morning was similar. Doesn't seem likely long suffering shareholders were selling much on Friday. Although I am curious where all the shares came from on Thurs afternoon. Anyway, the volume and trading dropped off dramatically Friday afternoon. And even this morning, it's very tame.
I expect we'll see better action through the week as new investors do their due dilligence and more info comes out from Agoracom, Frank et al.
