I've spent the past few hours reading some very useful GeoExpat threads on ETF portfolios and brokers. Given that (a) some people seem to genuinely enjoy debating one another's portfolios and (b) there's a lot of knowledge on this forum, I'm going to post my proposed portfolio for public admiration / ridicule.
Lump sum of US$100,000 then US$10,000 per month into:
IGLS (iShares UK Gilts 0-5 years) - 30%
CUKX (iShares FTSE 100) - 20%
VWRL (Vanguard FTSE All-World) - 50%
All to be bought through Saxo, redistributed periodically but otherwise held for 20+ years. I'm British and a lazy investor.
