Subject: Re: euros
One possibility one might consider having a look at is is one of the funds that tracks the "MSCI World EX-US Equal Weight Index".
I can't find a fund in the US (ETF or mutual) that tracks it, but there are several in Europe. One ETF is IE000OEF25S1 from Invesco. I find conflicting information on line, but a US person may be able to buy a UCITS ETF. (a registered European fund).

Sounds interesting, but the ETF from Invesco that you suggest is not “ex USA” and unfortunately I can't find any other ETF that tracks the “MSCI World Ex-USA Equal Weight Index” (UCITS would be suitable for me as a European anyway).
