as crowe pointed out and is publicly posted for all to see, JB writes of CDEX Inc, not of Celldex.
So it still could be a mistake by whoever records ticker changes.
If it's NOT a mistake, how did sexi cexi get around the use of the ticker trading letters - around not being able to use those letters in the past, and now being able to?
C'mon, JB ... speak up.
