I think the biggest barrier if you read the turnover, is Fridays. It so regularly gets dumped on a Friday - is it just DTs and STs hedging their losses/profits and unwilling to risk holding over the weekend? GDN has always had a history of being very volatile during the P & Ds over the years and some just wont risk the weekend hold!! Now seriously - based on the history of GDN, can you blame them.
