Compass EMP Funds recently launched 4 volatility weighted ETFs for investors seeking a change from purely market capitalization weighted indexes. Compass CIO Steve Hammers explains why the Compass EMP U.S. 500 Volatility Weighted Index ETF (CFA), Compass EMP U.S. 500 Enhanced Volatility Weighted Index ETF (CFO), Compass EMP U.S. EQ Income 100 Enhanced Volatility Weighted Index ETF (CDC) and the Compass EMP U.S. Discovery 500 Enhanced Volatility Weighted Index ETF (CSF) offer potentially higher rewards with less risk than traditional cap-weighted ETFs. Nashville, TN-based Compass launched 9 indexes in 2012 based on their methodology going back to 2003.
