You see that Q on the end of the symbol? That denotes bankrupt. And BIOAQ IS bankrupt. Their case is in the Federal Bankruptcy Court of Delaware. http://www.pacermonitor.com/public/case/24653251/BioAmber_Inc_and_BioAmber_Inc Which means BIOAQ shares are going to end up exactly the same way as your example of Egalet. Thanks for proving my point.
