ETF investors can also take the low volatility theme to broader overseas markets. The low-volatility ETFs have helped soften the blow from the global sell-off. For example, the the PowerShares S&P International Developed Low Volatility Portfolio (NYSEArca: IDLV) and iShares MSCI EAFE Minimum Volatility ETF (NYSEArca: EFAV) provide a low-volatile option for developed overseas markets.

Additionally, investors can target emerging market exposure through the iShares MSCI Emerging Markets Minimum Volatility ETF (NYSEArca: EEMV) and PowerShares S&P Emerging Markets Low Volatility Portfolio (NYSEArca: EELV).

However, potential investors should be aware that since these ETFs focus more more slow and stable companies, the low volatility strategy may underperform more growth-oriented stocks in an extended bullish rally.
