Were these buys hidden during the day to throw peeps off into thinking 1) more selling than buying was going on, so buyers stay away (this would aid and abet the shorters), 2) this would tremendously aid the shorters in and of itself to try and cover during a disastorous week for them, 3) shares bought or came upon by one broker issued to the shorters so as to cover, 4) just the fact all these buys were hidden is a serious, smoking gun problem. The volume definitely creeped up after hours. My detailed quote page on Scottrade had a mismatch in volume with the Trade page, all after hours.
