went through the open interest data for june contract of major stocks and in majority of the stocks the open interest bulit up was seen on days when the stocks were up and not down . This indicates that the often abused word short-covering rally may not come barring an odd icici bank ,jp associates , maruti , neyveli , dlf and ashok leyland where the oi bulit up was seen even on down days..if a rally comes through today it will be due to reasons other than short covering probably a long buildup..
