The underlying index for this ETF, the STOXX Vietnam Total Market Liquid Index (GTR, USD), is designed to replicate the returns of the Vietnamese equity market, specifically focusing on publicly traded companies. To maintain market efficiency, businesses failing to meet predefined liquidity criteria are excluded from the index. The weighting of each company is primarily based on its free-float adjusted market capitalization, which is then further adjusted by its 'Annualised Turnover Ratio' – a measure reflecting the median daily trading volume relative to its free-float shares over a specific duration. The index undergoes rebalancing twice a year, ensuring that no single component exceeds a 15% weighting.
