What is iShares Core U.S. Aggregate Bond ETF? 

iShares Core U.S. Aggregate Bond ETF (AGG) is an exchange-traded fund that tracks the performance of leading US dollar-denominated investment-grade bonds.  

At the time of writing this article, AGG has a net value of USD 76.5 billion. The fund was launched on 22 Sep 2003 on the NYSE. 

AGG is a fixed-income investment fund and offers dividend payouts every month. It is benchmarked against the Bloomberg U.S. Aggregate Bond Index which offers broad-based exposure to top U.S. debt issuers, including taxable, investment-grade U.S.-dollar-denominated bonds with at least one year until maturity. 

The Index is mostly comprised of one of three categories of bonds – U.S. Treasuries, corporate bonds, or agency mortgage-backed securities.  

Furthermore, holdings are weighted according to market value, with an emphasis on the largest and most liquid asset, rendering it an accurate benchmark for the entire U.S. investment-grade bond market.  

How has AGG performed so far? 

In the nearly 20 years since its inception, AGG has grown by a respectable 68.3%.  

On an annualised basis, the ETF has managed a yearly yield of 2.90%, close to the benchmark of 3.09%. Currently, AGG has a 12-month trailing yield of 2.22%. 

The fund remains highly popular and enjoys high trading volume with over 8 billion shares traded daily, as at 1 Nov 2022 [3].  

What are the holdings of AGG? 

AGG is composed of nearly 10,500 different holdings, with close to 70% of the fund’s value taken up by its top five holdings. 

By far, the largest holding in AGG at over 41% is the U.S. Treasury –. According to Morningstar, 22% of the fund’s assets carried a AAA credit rating as of April 2022; this is in contrast to the category average of 50% [4].  

The bond fund’s top 10 holdings are shown in the table above; notable entries include top investment banks JP Morgan, Goldman Sachs and Morgan Stanley; U.S. agency mortgage-backed debt instruments, as well as Bank of America. 

What is AGG’s expense ratio? 

AGG offers a 0.01% discount on the total management fee of 0.04% (management fee of 0;03% + acquired fund fees of 0.01%) – which means its net expense ratio is 0.03%. This is a fair rate for passively managed, fixed-income investment funds.  

For comparison, the similarly structured Fidelity U.S. Bond Index Fund (FXNAX) offers 0.025% expense ratio, while the Schwab U.S. Aggregate Bond Index Fund (SWAGX) has an expense ratio pegged at 0.04[5]

Why Invest in AGG 

agg bond etf,

Easier management 

The interest AGG receives from the bonds in its portfolio is collated and automatically paid out to investors. This saves investors from the need to keep track of different maturity bond dates and dividend payout schedules. 

As old bonds mature and become fully redeemed, AGG automatically adds new bonds to its holdings.  

Exposure to top investment-grade bonds  

The AGG is designed to track the Bloomberg U.S. Aggregate Bond Index, which is recognised as one of the best total bond market indices, and regularly used by bond traders and managers of mutual funds and exchange-traded funds (ETFs) to measure their relative performance. 

Accordingly, investing in AGG provides broad exposure to the U.S. bond market, including top investment-grade bonds – without the need to investigate several individual bonds.  

Portfolio diversification 

AGG allows investors to achieve a degree of diversification in their portfolios.  

As bonds carry lower risk compared to other assets such as stocks, investing in an ETF like AGG can be a good way to balance out an uneven portfolio.  

Low cost and low barrier to entry  

With an expense ratio of just 0.03%, AGG has a very low cost of investing, which may be attractive to some investors. However, while 0.03% is indeed low, this figure must be evaluated against the bond fund’s annualised returns of under 3% [6].   

Additionally, AGG’s structure as an ETF lowers the barrier-to-entry for investors, allowing investment at lower capital – especially at brokerages that offer fractional shares.  

How to trade AGG? 

If you’re planning to invest in AGG, you can sign up with an online brokerage that offers access to the U.S. bond market. Do a search on the broker’s website for “AGG” or “iShares Core U.S. Aggregate Bond ETF” to confirm that the fund is offered for investment.  

Before making a transaction, take note of any platform or broker fees that may apply; these are separate from the 0.03% expense ratio charged on AGG.
