SEC-registered and Rule 144A with registration rights are eligible; floaters, TIPS, convertibles and private placements are excluded. Constituents are market-value weighted; Treasury amounts outstanding are adjusted to exclude Federal Reserve SOMA holdings. Membership and weights are refreshed monthly on the last business day.

Investment Proposition

iShares Core U.S. Aggregate Bond ETF (AGG) provides broad, investment-grade U.S. bond exposure spanning Treasuries, agency mortgages, and high-quality corporates through a market-value-weighted, rules-based approach designed to reflect the taxable core fixed-income universe. The strategy seeks to deliver diversified interest-rate and credit exposures with low structural concentration and disciplined rebalancing, keeping turnover modest relative to more tactical bond allocations. Return potential is primarily driven by term structure and credit premium, with income distributed regularly; risk arises from duration sensitivity to shifting yield curves and spread moves. In early-cycle or disinflationary backdrops with declining policy rates, duration can support total returns, while late-cycle inflation reaccelerations or sharp yield spikes can challenge results. As a portfolio building block, AGG can serve as a core bond sleeve for balanced allocations, a ballast against equity drawdowns, or an income anchor for liability-aware mandates. Typical users include strategic asset allocators implementing policy benchmarks and income-oriented investors prioritizing stability; both often pair it with equity or credit satellites. A key risk to monitor is duration concentration that can amplify mark-to-market volatility when rates reprice quickly.
