I called Scottrade. Ethanex DID change their ticker to EHTE in combination with the reverse split. Scottrade has not been able to receive the new required certificate from the transfer agent yet, and no time frame has been given to receive this. I asked him how long this can take, and the broker was clueless. He said sometimes these microcaps can get things fixed in a couple days, but he has seen reorganizations that can take a year.
So, if you own Ethanex in a Scottrade account, you're not going to be trading this stock for an indefinite period of time.
I can only assume other brokerages are experiencing the same problem? If you have information on this, please let the rest of us know.....
