I admire your optimism. But let me dampen it! Sorry!
It will almost certainly be harder than you think
Fractions, for instance. Unless the registrar is registering fractions - which I will go ahead and assume they are not as the actual purchase will be made in whole units with A N Other taking the residual fractions - you won’t be able to transfer fractions. Unless (too complex to imagine) the A N Other transfers their portion of the share too in order to make the whole.
Confused?
Yeah, me too!
But the thought is interesting.
Would love to get the official word on this
