iShares Core 60/40 Balanced Allocation ETF (AOR) is an exchange-traded fund managed by BlackRock that seeks to track the S&P Target Risk Balanced Index, providing a diversified portfolio with approximately 60% exposure to equity securities and 40% to fixed income instruments for moderate capital appreciation, income, and preservation. The fund's core holdings consist of underlying iShares ETFs, including iShares Core S&P Total U.S. Stock Market ETF (ITOT) for U.S. equities; iShares Core S&P 500 ETF (IVV) and iShares Core S&P Mid-Cap ETF for large- and mid-cap U.S. stocks; iShares Core S&P Small-Cap ETF (IJR) for small-cap exposure; iShares Core MSCI EAFE ETF (IEFA) and iShares Core MSCI Emerging Markets ETF (IEMG) for international developed and emerging market equities; iShares Core U.S. Aggregate Bond ETF (AGG) for U.S. bonds; and iShares Core International Aggregate Bond ETF (IAGG) for global fixed income. It operates primarily in the global moderate allocation segment, targeting investors seeking a balanced, hands-off multi-asset strategy with semiannual rebalancing in April and October; the ETF was launched on November 4, 2008, and is domiciled in the United States with BlackRock serving as the issuer based in New York. In a recent operational change, the fund and its benchmark index were renamed from iShares Core Growth Allocation ETF and S&P Target Risk Growth Index, respectively, prior to February 19, 2025, to better reflect its balanced 60/40 risk profile.
