Look at http://messages.finance.yahoo.com/mb/ARIO.PK to get your head straight. It is very likely that the volume is so small today because there are few buyers at 0.0001. No buyers means you can't sell. And why is that? Is it possible the buyers have moved knowing the reputation of Janovec, who is a big crook? Very likely.
For sure, do not put much money up on this stock. The past track record of Janovec should put him behind bars with all the investors he has ruined. I know, because I have been in this stock in the last few years. My meagre investment is an effort to recoup what I lost, and yes, I am still hopeful it could pull out. But what is happening with the bid size/ask size investors should be aware of.
