if buyback is to be happen below 160/- levels than it should be open for atleast 1 to 2 months,i don`t think that srf share price will remains below 160/- level for 1 to 2 months,it might be that promoters are buying at current levels and they will refresh the buyback price to 250/- levels,soon might announce,at current levels the delivery base is good.other comments welcome.
