However, when accessing overseas markets, investors will be exposed to currency risks – a strengthening U.S. dollar or weakening foreign currency diminishes international equity returns.

Alternatively, investors may look at a number of currency-hedged international ETF options to capture foreign exposure while hedging currency risks. For instance, the Deutsche X-trackers MSCI EAFE Hedged Equity ETF (NYSEArca: DBEF) and iShares Currency Hedged MSCI EAFE ETF (NYSEArca: HEFA).track and hedges currency risk of Europe, Australasia and Far East countries.

For emerging market exposure, the Vanguard FTSE Emerging Markets ETF (NYSEArca: VWO) tracks the FTSE Emerging Index and the iShares MSCI Emerging Markets ETF (NYSEArca: EEM) follows the MSCI Emerging Markets Index. Additionally, the iShares Currency Hedged MSCI Emerging Markets ETF (NYSEArca: HEEM) and the Deutsche X-trackers MSCI Emerging Markets Hedged Equity Fund (NYSEArca: DBEM) track the developing markets while hedging against depreciating overseas currencies.

However, potential investors should be aware of the trade offs with these types of funds. ETFs that track alternative indices and international markets tend to have higher expense ratios. Additionally, since these currency-hedged ETFs utilize monthly options contracts to hedge currency risks, they will roll contracts to maintain the hedge, which can trigger taxable capital gains or issue capital gains distributions to investors.

Furthermore, given the elevated global volatility, investors may also consider a low-volatility ETF option. For instance, the iShares MSCI EAFE Minimum Volatility ETF (NYSEArca: EFAV) tracks EAFE country stocks that exhibit low volatility and iShares MSCI Emerging Markets Minimum Volatility ETF (NYSEArca: EEMV) targets developing countries. EFAV and EEMV have both exhibited reductions in volatility relative to their parent benchmarks.
