Vanguard U.S. Minimum Volatility ETF(AMEX:VFMV)

VFMV is actively-managed to provide low-volatility exposure to the broad US equity market. Although VFMV is an active fund, the portfolio manager follows a rules-based, quantitative approach to offer low-volatility exposure to US equities of all sizes. Unlike some competitors that merely screen for low-volatility stocks, the fund uses a proprietary model that considers common sources of risk. The aim is to minimize the total volatility of the fund, while maintaining diverse exposure to the US equity landscape.
