When someone posts that MAKE SURE they are making a distinction between companies that move up from the grey sheets BUT ARE NOT UNDER INVESTIGATION ie. started on the greys...and those that came from the pinks via suspension.
What I am talking about is a pink sheet stock that gets suspended, re-opens on the greys. They almost NEVER, if ever come back.
There are plenty of examples of uplists from the greys for the first example I list above. But that is not what this is.
