I put some of my money in a Pacific Rim index fund (Vanguard). While this has the normal stock market risks / rewards, it also diversifies into (mostly) Yen. Let’s say that 1 year from now the price of this fund is exactly the same as when I bought it, but the yen has gained 10%. Assuming no fees, I gained 10% on the investment. That is my understanding anyhow!
