before going ex-div, page-2

I thought EX-DIV date is actually Monday??
So theoretically, we'll see a 4c correction from the SP= 22-4= approx. 18c ??

Interested in any guesstimates/ opinions. Personally, the bizarre market activity on Fri and the assumption that CFS have close to completed their dumping... I see this closing on Monday COB at much higher than 18c... I reckon the 1st 20mins of trade monday might be a great chance to load more more if you are a holder/ buyer.
