Since every long that I know expects CTIX to trade in multi dollars and move up to be listed on NASDAQ in the not too distant future I don't think any of them has given selling a thought. They are looking under couch cushions and liquidating where they are able to take advantage of the shorts predicament.
Think about this, longs are focused on the science causing CTIX to mimic REGN http://finance.yahoo.com/quote/REGN?ltr=1
REGN is our model and the path that will lead longs to great wealth. Today CTIX is a penny stock with incredible upside and science that keeps on proving itself and we've only just begun. Go CTIX!!!
