Facebook shares are down more than 4pct today, falling to as low as $19.91, and currently dancing around the $20 mark. A stock that briefly traded as high as $45 on its first day is less than half that now.
It extends beyond facebook. It's related to the players that share common board positions. It is very difficult to prove but I can assure you there is collusion going on underneath the table to control share prices -- in my humble opinion.
I can see how they are doing it and could even explain it but that's a can of worms I just don't want to open. But if you want clues read my post from just over a year ago [webmasterworld.com ]
