Methodology and Construction
Both indices are constructed by selecting large‑ and mid‑cap companies that together make up roughly 85 % of free‑float‑adjusted market capitalization within their respective markets. Index constituents are assigned weights according to their share of this investable market. The methodology ensures representation of the most significant companies by size and liquidity.
Recent Changes and Trends
- Emerging Markets Index: Recent rebalances have included newcomers like China Citic Bank, Dian Swastatika Sentosa, and Laopu Gold. One rebalance recorded a 1.68 % turnover, with many deletions in China and sector shifts favoring Brazilian financials and Indian holdings.
- Performance Context: Emerging market equities have shown periods of underperformance relative to global equities, driven by factors like China’s economic slowdown, yet remain less expensive on valuation metrics. Some investors regard this as value potential.
