I presume this is addressed to me.
My HYP was initially built up long ago, before I founded TDL. It’s a very substantial portfolio and these days I am more likely to top-up existing holdings if I have some additional cash to invest. Consequently I do not hold every single share I select and WPP is not the only one shown in TDL that I do not hold personally. Going the other way, there are some shares I hold in my HYP which I have never selected in TDL.
Other reasons include my own rules regarding sector diversification and not over weighting sectors etc. to which I adhere. This also could cause me to refrain from purchasing a share I’ve selected if I’m already up to full weight in that sector from other holdings in the same industry.
So there can be several reasons why I do not hold any particular selection in TDL, none of them having anything to do with my views on the quality of the share.
