103991611 MillionDollarDivSeek : had the same question and thought - seems like many would try to game the system if that's the case since it's still up in premarket and the dividend cost only gets deducted during regular trading hours
so, in that case, to maximise profits, it'd be to sell during the premarket of the ex date and we'd get both the gains and double dividends in a way? am I understanding that correctly?
