Hello Phil
The cost of, or profit on, your original investment in Sky is not relevant for this purpose.
What matters is the amount of cash realised from the Sky proceeds and how this compares with the current average sector value in your portfolio. This calculation will vary amongst every reader that held Sky so I could not show the actual effect on each holder’s portfolio individually. What I could demonstrate was my method of how I dealt with it in those HYPs of mine which held Sky.
What I suggest is that you calculate your current average sector value, excluding the Sky cash. This sum is the maximum amount to invest in any new sector(s) so as not overweight them at cost. If large enough, the cash could be adequate for two new sectors or even more. This is what happened with HYP6 where it was adequate for two whole new sectors and then some left over with which I chose to top up GNK. It does not mean the same would apply to you necessarily.
Hope this helps.
