I have given up on what might happen on exdiv day.....there are a lot of outside forces that can affect the outcome. The DOW up or down, interest rate increases or decreases, oil, gold the $, elections, etc. If you trade this strategy every day through thick or thin, you just have to take each day as it comes.....something out of the ordinary is bound to happen most days.
I adjust my stoploss down by the dividend + franking credit as the worst scenario + a bit of commonsense (try to anyway), then adjust my trailing stoploss at the end of each day.
Normally when a profit is announced, if the dividend has increased, the profit has increased & there is a good outlook for the future, then the price usually jumps, no matter what the trend was prior. These are the stocks I trade the most, but since I have been posting my trades on forums, the market has been so good that almost every stock that declares a dividend has been a winner......so when the market slows or even starts to go backwards, more care has to be taken with selections. There has been indications already this reporting season that more care must be taken with selections.
As to exdiv day results, there seems to be no pattern.......what is great one season can be a "dog" the next. On google search engine there is a study as follows
exdiv day behaviour interesting but....its 40 pages.
Yesterday
CBA traded exdiv with a div + fc of 121.43 & was down 130.0
RUP traded exdiv with a div + fc of 18.57 & was up 14.0
WES traded exdiv with a div + fc of 75.71 & was down 75.0
I sold CBA on Friday (the day before exdiv) because it has a habit of taking too long to return to its price prior exdiv, with capital tied up too long with interest marching on.....it may prove me wrong being up 27.0 today atm.
Today
CCL traded exdiv with a div + fc of 22.14 & atm is down 20.0
CXP traded exdiv with a div + fc of 11.43 & atm is stable (no up or dn)
