Egon [ @EgonKuhn ] & @Spekulatius,
@Spekulatiuss points above are valid.
Related to tax efficiency, @Spekulatiuss commment may as far as I understand relate to you, Egon [ @EgonKuhn ], while it is not relevant for me, holding this basket stuff in Danish tax deferred accounts [I get credit in Danish taxes for foreign withheld dividend taxes].
Related to why even try? I'll mention I have looked at the rest of Europe at that time, also, but never engaged in anything at that time.
In stead of trawling through long lists of listed companies I did download to a spreadsheet the total portfolio of NBIM [Norges Bank Investment Mangement], and turned on some filters [country, real estate] to take a tour in Europe looking around. [Link ]. [NBIM stocks likely picked by one of many investment mandates, Nicolai Tangen is too busy doing podcasts!].
I did not feel comfortable at any of that stuff, knowing nothing about local conditions, regulation and such.
