"How did it compare to the asx market as a whole would be a good comparison?"
Are you serious? If the whole market plunged 50% the day before based on an event described vaguely as a 'typo' or a 'miscommunication', I'd expect a near full recovery.
The fact is we've plunged and stayed there. Today might be good for anyone who bought in yesterday but it was no great vote of confidence for the management of CCU.
