IDLV aims to provide low-volatility exposure to developed markets excluding the US and South Korea. The fund begins its selection universe with the S&P Developed ex-US & South Korea Largemid-cap Index constituents. Eligible securities are then ranked inversely based on calculated volatility over the trailing twelve-months. The top 200 least volatile securities will be included in the index. The fund uses a volatility-based weighting scheme so that the least volatile stocks receive the highest weights. Index rebalancing occurs on a quarterly basis.
