Sure seems like a lot of 3's trading this week especially with big blocks changing hands. I thought I would get in on action and buy 400,000 shares for son's account but unfortunately for past several days orders expired since probably too many orders ahead of mine. I hope 3's is not the new norm but I thought that at each level down. Still hopeful on company news that will shake up the market in a positive direction.
