GSIE applies multifactor methodology to the developed ex-US space. The fund combines four different sub-indices: value, quality, momentum and low volatility into one ETF. Despite the active moniker, the ETF tracks an index from its issuer. All four of the sub-indices pull their constituents from the parent MSCI World ex USA Index, giving each member a weighting based upon factor criteria (small-caps are excluded per the parent index). Criteria include book value, sales and cash flow scaled by share price, profit/assets or ROE, risk-adjusted returns, and daily standard deviation of returns. The four evenly weighted sub-indices are then combined to create the index, any overweights to a particular name from one sub-index will cancel underweights from another. As such, the fund may exhibit moderate rather than radical deviations from the cap-weighted market.
