iShares Asia 50 

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. Stocks are also given weight based on their float market cap. However, any single issuer is limited to 22.5%, and the combined weight of all issuers that individually exceed 4.5% to a maximum of 45%. The index is rebalanced quarterly. Following December 23, 2024, AIA tracked the capped index version, the S&P Asia 50 Capped Index.
