MFEM aims for increased exposure to outperforming investment factors in the emerging market space. It calculates a fundamental weight using four fundamental metrics: current book value, last five years of de-levered sales, cash flow, and dividends plus buybacks. Each security is also scored on five investment factors: value, low volatility, quality, momentum, and size. These factors are used to create five sub-portfolios. For the value, quality, and low volatility portfolios, stocks are ranked by the factor score. The top 25% by fundamental weight are selected. The momentum portfolio selects the top 50%. The size portfolio includes all of the small-cap firms from the other portfolios. All sub-portfolios are weighted by fundamental weight. The factor portfolios are equal-weighted to start, with weights adjusted based on momentum and long-term reversal signals. The index uses a rolling rebalance, only rebalancing 25% of each sub-portfolio every quarter.
