If you are so sure about the fact that "the shares will be cancelled", this to me sounds very much like the ticker symbol of the company, with or without a "Q" will be delisted!
So for a novice, the document linked is very confusing. Where exactly have you read that there will be no recovery and they will be wiped out (you mean the company employees or shares?)...
If you have read all this, I am surprised if there are other shareholders or not saying this will rocket once the company is out of CH11?
