biolover. AIS short interest jumped on July 2010 from around 1MM to over 4.5MM when they were added to the Russell 3000 and stay high since(climbing as the price climb)
Some say it is hedge by long positions, since they have no options, but those are speculations only.
I have been long AIS since 2008 and I think fundamentals are getting better every year Regards.
AIS..$2.32 December 8th will be an excellent day for the company. Data definitely looks strong, but I also put a lot of importance in the partnerships of TEVA & WATSON pharma. Really good plays here. Some are good for catalyst run ups & others to hold through PDUFA dates.
