iShares Core U.S. Aggregate Bond ETF (AGG) is an exchange-traded fund, which is an alternative investment instrument to similar mutual funds. AGG aims to track the performance of an index composed of all U.S. investment-grade bonds, namely – the Bloomberg US Aggregate Bond Index. It is a liquid fixed-income asset class, allowing investors to trade its shares similar to a usual stock. Like many others, it is a pool of bonds issued by various companies, offering a more diversified investment opportunity. It can be considered a more attractive alternative to comparable mutual funds, from related costs and liquidity perspectives. 

Characteristics, Performance Analysis, and Expectations


Launched in September 2003 and managed by iShares, AGG offers a very high-quality portfolio, with the below holdings:

  • Nearly 70% of its assets are invested in AAA debt (the highest possible rating). 
  • The remaining 30% is invested in other investment-grade bonds

Instead of cherry-picking among various bonds issued by the government or individual companies, trading shares of AGG or other ETFs provides investors with exposure to-constructed bond portfolios. Meanwhile, the portfolio risk is substantially reduced through a higher diversification, while the costs related to such a single trade are much lower compared to multiple purchases of various bonds to construct a comparable portfolio.

Another important advantage characteristic of most ETFs is their low expense ratio. For iShares Core U.S. Aggregate Bond ETF it is merely a 0.04%, so the payable annual cost is calculated based on this ratio and the volume of the AGG shares you own. This fee is in the average range compared to most bond ETFs and is used by the fund manager to cover its operating expenses. 

Currently, the volume of the net assets of AGG amount to around USD 86.8 billion, which includes all of its bond holdings, cash, and other financial instruments. This makes it one of the largest bond ETFs globally. 

At the same time, AGG offers an attractive annual dividend yield of 2.32% as of January 2023, paid on a monthly basis. Thus, it is an attractive investment option to be considered by investors looking for index-linked bond portfolios offering good and frequent dividend payouts.

Generally, the ETFs are traded similar to usual company stocks, based on their price per share which is called net asset value or NAV in the case of ETFs. It is calculated by deducting the given ETF’s total liabilities from its total assets, which will result in the total net assets (TNA) of the fund. Then the TNA should be divided by the number of outstanding shares to show the current NAV at the opening or closing of the market each day. Thus below are key numbers for  AGG:

  • TNA amounts to USD 86.76 billion.
  • It is distributed through its 10,000+ holdings. 
  • The number of outstanding shares is nearly 866 million pieces.
  • The closing price of the last trading day was USD 100.28 per unit.

Performance Analysis

The ETF started the year 2023 positively with a +2.84% year-to-date (YTD) return. Indeed, it’s driven by the overall market rebound following the previous year-end drop and is based on some positive expectations of a slow-down in the inflation rate. Provided that the key benchmark indexes have been moving in the same direction and within a similar range of 1.8-3.2%, AGG’s above-mentioned performance can be linked to the general market trend. 

It’s important to emphasize that ETFs like AGG are not targeting capital appreciation or share price growth, provided that they are fixed-income debt instruments, holding bonds issued by various companies. Instead, AGG is historically offering stable and good dividend yields, which are paid monthly. The dividend pay-outs are made on the basis of the incoming debt servicing proceeds received from the issuers, which are well-established and largely capitalized enterprises with solid business models with stable growth perspectives.

In fact, if we try to compare iShares Core U.S. Aggregate Bond ETF since its inception back in 2003 with the performance of the broader market and its main indices for the same time period, except for the exceptionally stormy financial year 2022 for the reasons we are all aware of, then we’ll witness notably lower volatility in AGG’s NAV or share price than in those key market indices. 

This can be comforting for investors, who are seeking diversification of their equity-denominated portfolios, along with less price volatility involved and with additional dividends received on top.


Based on AGG’s past performance and its above-mentioned characteristics, our forecast of this ETF for 2023 would be that it will continue to remain less volatile compared to the rest of the broader market. 

Currently, the markets are extremely sensitive to the news on inflation and related national bank decisions on interest rates. However, such decisions have a more limited impact on AGG and similar bond ETFs, compared to the equity markets. 

Additionally, we think that the inflation will stay with us for longer, however, it’s expected to slow down in 2023, which would be positive news bringing some stability to the markets in general.

Risks associated with AGG

The market risk is the overall risk related to multiple factors driving the financial markets, which may negatively affect your investment. Among such factors are the interest rates, sharp drops in ETFs share price (caused by an excess supply or strong decline in demand for the ETF or its major holdings), inflationary pressures or foreign exchange fluctuations, as well as adverse economic and geopolitical events which may have a negative impact on the financial markets.

Since the iShares Core U.S. Aggregate Bond ETF is mainly holding bonds issued by large companies it is affected by their overall financial performance, as well as any changes in their credibility and capacity to service their debt. Negative news related to companies and the bonds which AGG holds, such as deterioration in cash flow, missed targets of quarterly earnings, revision of announced financial estimates, lawsuits, etc. will certainly impact the ETF’s share price negatively.

Hence, prior to undertaking any investment, it is recommended to do your own small research for understanding the market-related risks, as well as other risks described below, which may have an adverse impact on your investments.

Credit risk is usually associated with the risk of the counterparty failing to pay its obligations. As a fixed-income ETF holding just bonds, AGG is exposed to multiple counterparties which may potentially fail to fulfill their financial liabilities partially or completely.

However, as we are talking about investment grade bonds only, nearly 70% of which hold the best possible – AAA rating, the probability of default of issuing corporations is minimal. Nevertheless, it is important to look closer into the ETF’s holdings for understanding the degree of the credit risk involved could be, prior to taking your final investment decision.

Generally, under liquidity risk, we should understand any circumstances which may create obstacles for fast and complete cash-out of your investments once you decided to do so. Liquidity risk related to large ETFs like iShares Core U.S. Aggregate Bond ETF provided its overall credibility, degree of high diversification, multimillion share trades per day, and many other factors are considered to be extremely low.

Valuation risk is associated with possible inaccuracies in the pricing of a given financial instrument. When considering ETFs, this type of risk is relatively low provided that ETFs are primarily traded through stock exchanges, where the price is determined by the relation of actual supply and demand for any given moment of time.

Nevertheless, there are still some internal or external events, which can impact the given ETF’s share price, depending on its underlying holdings. Still, particularly in the case of AGG and its solid holdings, the valuation risk is quite low.

Frequently Asked Questions

Not really. Like any other exchange-traded fund, these ETFs are pooled investments consisting of various bonds, depending on the fund’s focus. Investors can trade bond ETFs like usual stocks through major exchanges.

3. Does AGG pay dividends and if so, how frequently?

The amount of the pay-outs depends on the actual performance of the issuing companies during the last 12 calendar months, the size of the coupon, and other payments to AGG, etc. Hence, it is actually based on the interest income earned on the total holdings of the fund’s portfolio.
