Some bought this stock at $100 per share 12-13 years ago. It traded down to $3. I bought 4 years ago at $6.50, sold at $5. Bought back in in $4 range, then dumped in $3 range in fall of 2012. It moves wildly because of no float. Insiders know that after almost 20 years without a successful product, or any profit, its days are only sustainable by getting cash against increasing stock prices from newly duped investors. Current buyers are the new dupes. Watch insiders sell their personal holdings at these new prices every chance they get. If you think ADEP is new and great....look at its history of "restructurings", stock price declines, insider sales, poor product sales, etc. iRobot eats their lunch on military contracts.
