It has been observed that FII is selling/shorting on (mostly each Friday or beginning of weekly/monthly expiry) and buying/short-covering at each Thursday of the Ending of weekly/monthly expiry.
Has any body observed as per FII data details available on NSE or NSDL??
Base on index movement in the week either FII buy or short and keep rotating their fund with profit booking..!!
Do confirm above observation is in line of different??
