As we know before ex date price usually rally, so i did experiment with my $OVERSEA-CHINESE BANKING CORP(O39.SI)$BullishPrevious div i sold before ex date, bought $12.23 sold $12.37 i thought it will dip alot (scared) so i profit only 0.14 while div 0.28.Bought back after ex date $11.93 (lucky)The recent div, i did not sell before ex date, the highest rally $12.46, i just keep it, and today price has moved up to $12.36 ! Means i got dividend 0.28 and the price almost backto pre-div price.I also sold my $WILMAR INTERNATIONAL LIMITED(F34.SI)$before ex date $4.18 thinking to buy back when dip, now after div the price already 4.18 again ! So i can not buy back for n
