@ Gems - I always ask people one question at a time like this. Do you have a better counter, one that you understand and believe will perform extremely well in mind? Then you can cut your losses and take your money there. In your case, I don't believe you have (from your question on the best counter to put your balance in). I would suggest you stay put, don't take up your rights, wait for the share price to drop significantly and then average down at that point - as the rest of us are getting in. KCB is not about to collapse. But you can be sure the share price will drop further before rising!
I'm sure some Wazuarian will ask why you should simply not sell the shares (at approx 18.5) and then use the same money (plus some more) to get back in at a lower price - say 14 - 15. To that I have no answer. I find it hard to accept a loss and thereby choose to hold (for a long time)
if the fundamentals are right. Best approach? Of course not. But that's how I do it.
To be honest with you, this KCB share is a terrible thing to have at the moment. Most of us are just lucky we are not in. If we were we would be probably more confused than you!
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
