EMSG provides exposure to emerging-market stocks with higher ESG scores. It aims to avoid country or sector bets by maintaining market-like weights to each of these buckets. The index starts with large- and mid-cap stocks and excludes certain industries (alcohol, gambling, tobacco, nuclear power and weapons). It ranks the remaining stocks by ESG scores which includes a controversy component, and then by market cap. Within each sector, the index selects the highest-ranking names until the accrued market cap reaches 50% of the total, effectively screening out ESG laggards. Selected stocks are weighted by market cap within their respective sector. The index undergoes reconstitution in May and rebalancing in August, November and February.
