Yes, what is up with that? Typically my MSGi shares calculate to some dollar value, but now it is showing $0 in my Scottrade account. Maybe it is just a Scottrade issue.
I keep track of all my stocks on Yahoo Financial and I see a last trade at $0.004 for a big 20 shares total for today, but I have never seen a bid or ask since it went on the greys.
I thought that was the point of being on the grey sheets - that you can't have market maker(s), because the SEC won't allow it. Maybe it just shows bid / asks in the online trading platforms.
