ETF investors can also take the low volatility theme to broader 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 on more slow and stable companies, the low volatility strategy may underperform more growth-oriented stocks in an extended bullish rally.
