The Dow Jones Industrials (DJINDICES:^DJI) has been extremely volatile during 2015, but overall, the average stands almost exactly where it began the year, giving investors no return for the risk that they've taken on. That's bad news for investors who stay close to home in their investment portfolios. But for those who've been willing to venture into certain international markets, there have been opportunities for them to profit more extensively.

In the following slideshow, you'll learn about seven different international markets that have picked up at least 5% this year in U.S. dollar terms, overcoming currency-based headwinds that, in most cases, have put U.S. investors at a disadvantage compared to their foreign counterparts. There's no guarantee these markets will keep outperforming the Dow, but it's worth it for investors to take a closer look at these overseas opportunities and decide for themselves whether to consider venturing beyond the borders of the U.S. in search of larger returns in 2016 and beyond.
