There are many ETF choices in the multinational, regional and single country sector from which to choose. We've cobbled some good choices together. When viewing the AUM (Assets under Management) for these funds you'll note how popular these sectors must be. This is due to the high interest with globalizing investment portfolios for most investors.
There is a consistent mix of global (including U.S.) to international (ex-U.S.) ETFs to consider. Beyond this, most ETFs in this sector have similar characteristics and results. Some may be skewed given exposure to areas with better recent performance (U.S. inclusive) than others (eurozone).
