The "going concern" note exists in many ASX companies (type "ASX" & "going concern" into google). People would be surprised at how many of these there are. It basically just means there needs to be a turn-around story ("if you don't do X, then Y might happen"), and CRE have written a bunch of stuff that they're doing to turn this ship around. Maybe some of the large insto's have rules around how much they're allowed to invest in a going concern company once they've been alerted to it- hence the sell off (I have no idea about that- just a thought).
This is where opportunists come in. They see the 70% sell-off, they see hoew the company has responded to the "going concern" note, and shares change hands. If the company just does a few things differently, as per their response, then it will cease to be a going concern, and be back on track.
