Xoma makes money when the stock goes down. Xoma must be shorting the stock. Last Q they said they lost money when the stock went up. I dismissed it but I should not have. It makes sense given their strange actions of promoting the company and then a 180 degree to drive and keep the stock down. They were the ones shorting at 4 and now covering. Easy way to accumulate others wealth. It explains all of the odd behavior.
