Well, there you have it. Dropped to under R20 - should recover a little today. But doubt it, I would TOTALLY take up the offer. In my opinion, the current share price should drop even more. As you mentioned with more shares being offered as well as the offer price. I wont even buy at R20 now
Not sure why there is so much speculation on the price or what to do with you rights. Rights issues don't create or lose value for shareholders, the maths behind the ex rights price is actually very simple go and read about it.
The rights price now is 7.85 and sub price is 11.28 so that gives a converted price of 19.13, currently price is 19.05 so rights are slightly overvalued.
