Hello, I'm reading asset allocation books (from a USA investor perspective). They say to buy some international ETFs. Do I have to worry about currency rates? I think the dollar is of intermediate strength right now. I would reason that I should buy international ETFs when the dollar is strong. That way you get more for you money. Is that true? It looks the like the major ETF providers have some nice funds that cover Europe, Asia, etc. Just not sure if now is a good, bad, neutral buying time for these. Thanks.
