It's a good quote, but you need to use it properly. It obviously (well, perhaps it's not obvious to everyone) means 'be greedy when others are *irrationally* fearful'. If the fear is justified, it makes sense to stay away. Companies do go to zero. People generally become fearful before that happens. Obviously that's not a time to be greedy.
CPH is not a company which was well run and solid, generating great profits with a proven business model for a long period of time, only to be dealt a temporary setback. It has always been overvalued, never generated anything like a net profit, and through smoke and mirrors it might have been easy to imagine it having a bright future, this has never been demonstrated and as time goes on and the smoke clears it just becomes more obvious that there's plenty of reason to be legitimately fearful (which is completely different from irrationally fearful) and I see no reason to be greedy here. Legitimate greed is fine, irrational greed will burn you. The only potential greed I see here is irrational, the type which burns people.
