iShares MSCI All Country Asia ex Japan ETF (AAXJ) is an exchange-traded fund that seeks to track the investment results of the MSCI All Country Asia ex Japan Index, which comprises large- and mid-capitalization equities across developed and emerging markets in Asia excluding Japan; the fund employs a representative sampling technique to replicate the index's performance by investing primarily in component securities or those with substantially identical economic characteristics. Managed by BlackRock Fund Advisors and issued by BlackRock, Inc. under the iShares brand, AAXJ provides diversified exposure to sectors including information technology (semiconductors such as Taiwan Semiconductor), financial services, consumer discretionary, and communication services, with key country allocations to China (approximately 28%), Taiwan (22-23%), India (16%), South Korea (12%), and others like Hong Kong, Singapore, and Southeast Asian markets. Launched on August 13, 2008 and domiciled in the United States with primary listing on NASDAQ, the ETF has approximately $3.3 billion in assets under management, a net expense ratio of 0.72%, semi-annual distributions, and around 920 holdings as of late 2025. Available to investors in markets including the United States, Chile, and Mexico, it targets institutional and retail investors seeking broad Asia ex-Japan equity exposure without Japan, blending growth and value stocks across market capitalizations. No major structural changes, such as mergers, rebrandings, or index alterations, have been reported for AAXJ in the last 1-2 years, though BlackRock has pursued broader iShares platform expansions including new active ETFs in infrastructure (iShares Infrastructure Active ETF in July 2025), liquid alternatives (iShares Systematic Alternatives Active ETF in December 2025), and equity conversions (iShares Dynamic Equity Active ETF and others in September 2025), alongside strong year-to-date performance of approximately 27-28% driven by regional growth in semiconductors and technology as of October 2025.
