The ETF invests primarily through underlying iShares funds, including iShares Core Universal USD Bond ETF (IUSB, approximately 59%), iShares Core S&P 500 ETF (IVV, approximately 17%), iShares Core International Aggregate Bond ETF (IAGG, approximately 10%), iShares Core MSCI International Developed Markets ETF (IDEV, approximately 8%), and iShares Core MSCI Emerging Markets ETF (IEMG, approximately 3%); its portfolio emphasizes U.S. bonds (48%), U.S. stocks (21%), and non-U.S. bonds (18%) for income generation and capital preservation. Launched on November 4, 2008, and domiciled in the United States, the fund operates globally through its underlying exposures to U.S., developed international, and emerging market assets; it is issued by BlackRock under the iShares brand and trades on NYSE Arca with a net expense ratio of 0.15%. In recent years, the fund underwent a name change from iShares S&P Conservative Allocation ETF, reflecting its alignment with BlackRock's Core series, while maintaining semiannual rebalancing in April and October; it has seen steady institutional ownership growth, with major holders including Raymond James Financial, Cetera Investment Advisers, and LPL Financial, amid broader BlackRock model allocation adjustments in 2025 that influenced related ETF strategies without direct alterations to AOK's mandate.
