AIA is fairly straightforward: it is essentially a mega-cap fund that offers exposure to 50 of the largest companies in Asia. Only companies from four major Asian countries, mainly, Hong Kong, South Korea, Singapore, and Taiwan, can be included in the fund. It's a concentrated play that screens constituents by liquidity and market cap though, as is usually the case for some S&P indices, the stocks are personally picked by a committee before being included in the index.
