PIMCO RAFI Dynamic Multi-Factor U.S. Equity ETF(AMEX:MFUS)

MFUS is a US-focused, multi-factor fund that aims for increased exposure to outperforming investment factors. The methodology calculates a fundamental weight (a stand-in for market cap) for each security in its universe, using four fundamental metrics: current book value, and the 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. For the value, quality, and low volatility portfolios, stocks are ranked by the factor score and 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 other four portfolios. All sub-portfolios are weighted by fundamental weight. The factor portfolios are equally weighted to start, and the dynamic element of the index adjusts the weight of each factor based upon momentum and long-term reversal signals. The index uses a rolling rebalance, only rebalancing 25% of each sub-portfolio every quarter.
