Investors looking to diversify their portfolios with foreign equities can choose from a wide selection of mutual funds with strong track records of low volatility and solid performance. Recently, international equities, especially those from emerging markets, experienced a lot of volatility due to a slump in commodities prices, slowing the economy in China and divergent monetary paths between the U.S. Federal Reserve and the European Central Bank.

As worries about slower global economic growth will likely persist into 2016, investors can still find mispriced investment options overseas with attractive valuations. At the same time, investors should be careful not to underestimate the havoc in worldwide capital flows that can be caused by the Fed's possible decision to raise the interest rate in 2015.

Investing in international equities exposes investors to currency risk, where fluctuations in foreign currencies can wipe out or even make negative favorable returns generated in other countries' currencies. In 2015, many currencies, including the euro, the Japanese yen and the Chinese yuan depreciated against the U.S. dollar, and this trend may persist in 2016. To obtain protection against currency risks, investors can choose funds that hedge their foreign currency exposure.
