reading comments on the other thread referencing the sell off yesterday and I note now a partial recovery today I am wondering is the sell off was due to the 45 day rule for franking credits (ex dividend date plus 45 calendar days to be held at risk). the stock sold down to around 1.50-1.51 which was the price point it broke through around 45 days ago so I am thinking that some who bought in for the dividend held on past the 45 days and sold off as they has secured their dividend and franking credit and then got out at levels still around same or above their entry price point. if this is the case then it may be good to hop in now and ride the recovery.
