agreed.
Its basically a balance between taking advantage on tax on dividend income vs. avoiding tax leakage on US dividends. Since MSCI USA dividend yield is continuously going lower and lower (stands at 1.2% now), the dividends in US stocks have less impact.
It will 
Sounds true for many mid-level managers or experts at work (or online or where-ever), as well, so it’s actually a very realistic response 
Off-topic career insight: Pointing that out in corporate life too often can get you into trouble.
For my 3a, I can’t pick individual regions and just ignore it for the allocation, only update the total balance once a year.
For VB (only 1 so far) there’s a simple allocation (CH and Europe): I ignore CH part in my allocation, but add the Europe value to my Excel where I compare as-is and to-be values to determine what to buy next.
Meaning no re-balancing in VB, but I take it into account for the taxable account.
Interesting discussion. So, what’s it now? Should you go for UCITS if you cannot reclaim the full (=100%) WHT, or if you can reclaim little or no WHT?
If you choose a low TER (comparable to VT) ETF domiciled in a country with a tax treaty that reduces the withholding tax (WHT) to 15%, such as Ireland, the outcome will be the same as with a US ETF, where you cannot reclaim the 15% WHT due to other tax deductions.
The private mortgage interest deduction will be abolished as a result of the last vote, so if that was why you could not reclaim the WTH, you might be able to in a few years.
If you can’t get any DA-1 credit, UCITS world ETFs with similar fees are actually better than US world ETFs as you don’t lose 15% US WHT on ex-US dividends.
Yes. If there is no WHT to be reclaimed then UCITS would be better
WEBG.SW or a mix of WRDUSW + XMME
Ah, yes, I see. UCITS only pays Level 1 tax on ex-US dividends. Thank you for correcting me!
