I know this is just an example, but one thing to watch out for is currency risk. The example here is a USD fund. There’s also a Euro (hedged) version of the same fund if that suits you better - https://www.justetf.com/servlet/download?isin=IE00B441G979&documentType=KID&country=UK&lang=enIn Degiro, login, click search, type msci world and they're all there e.g.

Hedging is not free and paying such fees over the long haul will impact your returns. I tend to treat the hedge independent of the investment. If I expect to draw down say 30k this year, then I'll hedge that rather than the portfolio.
