Investors have jumped on the smart beta investment train for a number of reasons, including risk reduction, return enhancement, improved diversification, cost savings, specific factor exposure and income generation. Looking back, some of these factor-based or smart beta strategies have been adopted by many investors over the years.

REFA allocates over 31% of its weight to Japan and 13.7% to the U.K., two markets that are attractively valued relative to the U.S. France and Germany, the Eurozone’s two largest economies, combine for over 26% of the ETF’s weight.
