ELV attempts to provide a lower-risk play on emerging markets, eschewing the market-cap-weighting mechanism in favor of one centered on volatility. The underlying index consists of the 200 least volatile stocks (over the trailing 12 months) of the S&P Emerging Plus LargeMidCap Index, meaning it leans heavily towards a portfolio consisting of large- and midcap stocks with low volatility. Also, industries with historically low volatility receive significant overweights due to the funds inverse-volatility-weighted method. Overall, this is a viable fund for investors looking for this specific exposure. ELV uses a full replication method to track an index that is rebalanced quarterly.
