DFRA invests primarily in US-listed companies of all market capitalization that are included in the real assets industry group. Sectors that comprise this group are as follows: real-estate related sectors, infrastructure-related sectors, commodities related sectors, and natural resources related sectors. Eligible securities are scored depending on their ability to generate profit and pay dividends using a fundamental evaluation that includes (1) quality of earnings (2) free cash flow profitability and (3) dividend yield. Those that represent the top 25% of the scored equity universe are considered for inclusion. Target weight is allocated to each security based on the combination of the three factors and market-cap. Based on the target weight, the index selects up to 75 stocks or until 90% of the cumulative security weight has been included, whichever occurs first. The fund may also invest in derivative instruments to maximize gains. The index is rebalanced and reconstituted quarterly.
