The Zacks Multi-Asset Income Index selection methodology is designed to identify companies with potentially high income and superior risk-return profiles. The objective of the Index is to select a diversified group of securities with the potential to have a yield in excess of and outperform, on a risk adjusted basis, the Dow Jones US Select Dividend Index and other benchmark indices. The Index constituent selection methodology utilizes multi-factor proprietary selection rules to identify those securities that offer the greatest potential from a yield and risk/return perspective while maintaining industry diversification. The approach is specifically designed to enhance investment applications and investability. The constituent selection process, as well as the ranking, reconstitution and rebalancing of the Index, is repeated quarterly.
