I could be wrong, but I think players are feeling that MW/Citron are unlikely to publish anything in the last half hour before the close.
Given that, anyone who shorted or bought puts looking for Citron-2 today is probably looking to cover and reload. Similarly, anyone who was holding off buying today thinking that Citron-2 would give them another drop before the close is now rethinking.
Something still could come out over the weekend, but a strong company response seems more likely than anything powerful from MW/Citron/????
Hence the EOD run.
If I could afford to buy all of them, I would not need to buy any of them and I sure wouldn't be spending time on the message boards!
