FYI: Foreign stocks bear an additional layer of risk stemming from changes in foreign-exchange rates, making them more volatile than their U.S.-listed counterparts. But currency-hedged international-stock funds allow investors to benefit from global diversification without taking on extra risk. Currency-hedging won't always help performance and could hurt tax efficiency, but it should consistently reduce volatility.
