$DTSS Maybe my theory about tax loss selling is true or maybe it's not, but if the after hours failed rally on Dec 11 was a lot of tax loss selling, because of the wash rule they can't buy it back until Jan 12. That's for USA. China allows tax loss selling but I can't find if they have a wash rule. It's possible the heavy selling after hours on Dec 11 was just those who were at a loss from 1. 80 and up getting out at a smaller loss . About a million shares traded after hours on Dec 11.
