"Can you,,, be sure that you can clearly enumerate what every share you hold is actually worth to you?"
"If the famous Mr Market offers you 5% premium, do you bite? 10%? 40%?"
Premium depends on what I paid for it.
"Have you considered CGT?"
"Where do you reinvest, when they're bidding everything up?"
Depends what's available.
If nothing sensible were available I'd hold my horses.
That would be, for me, a new experience.
