MILN invests in companies that are determined to have significant exposure with the millennial generation's spending habits. The index uses a proprietary fundamental research process to determine which spending categories are relevant to millennials. These categories include clothing, entertainment, travel, food, education, financial services, housing, and health. The portfolio will have a maximum of 15 stocks, a minimum of five are selected for each spending category. US companies with relevant exposure to these categories are scored by the level of their exposure. Firms determined to have significant exposure to the stated spending categories are then scored by a proprietary scale that determines which companies have a higher focus on millennials. These selected companies are weighted by market cap, with a maximum of 3% and a minimum of .3% for any given holding. The index undergoes annual reconstitution and rebalance.
