FYI: The benefit was obvious in late 2014 and early 2015, when foreign stocks were rising, but their value in dollars was being undercut by weakening foreign currencies. European stocks returned 7.4 percent in euro terms during 2014, for example, as measured by the MSCI Europe index. But each of those euros was worth fewer dollars, so the average European stock mutual fund lost 7.3 percent in dollar terms that year.
