I haven't been following them. Have they had a recent R/S? Sometimes, it takes awhile for the shares to be traded after an R/S. That type of DTC problem is usually short lived.
Other times a stock can have a global lock, or "Chill", which is usually permanent.
I'd have to do some research to see which situation applies to them. It may even be both.
Call your broker and ask whether or not they have a global lock or "Chill" in place.
Hmmm... Just did a quick google search and it seems the company mentioned becoming dtc eligible back in April 2011. If they aren't eligible now, you are probably looking at a global lock or "Chill". That isn't a good thing at all.
