For many investors, the Barclays U.S. Aggregate Bond Index
serves as the most recognized benchmark for fixed income returns. However, in the low-interest rate
environment of recent years, investors have increasingly looked outside the Agg to supplement income in meeting their investment goals.
In doing so, they introduce additional risks and different sources of volatility
that need to be carefully understood. In response, WisdomTree collaborated with Barclays to create a rules-based index—the Barclays U.S. Aggregate Enhanced Yield Index
(Agg Enhanced Yield)—that broadly retains the risk characteristics of the Agg while enhancing the income potential of the portfolio.
Enhancing Income Potential of the Agg
Yield can typically be increased by shifting exposure along any of a number of risk dimensions, including sector exposure (Treasury
), interest rate risk (duration)
and credit risk
The Agg Enhanced Yield uses a rules-based approach to reallocate across 20 distinct subcomponents in the Agg, seeking to enhance yield while maintaining a similar risk profile. This strategy allows an investor to focus on the investment-grade
credit universe, without having to dip into the high-yield
segment of the market to enhance yield
Yield and Duration Comparison, June 30, 2015
As we show above, the Agg provides a variety of opportunities for income across various sectors and interest rate risk profiles.
• Across the yield curve
, debt guaranteed by the U.S. government tends to have the lowest levels of yield per unit of interest rate risk.
• Next, securitized debt
or bonds backed by a pool of receivables such as mortgages can provide a modest lift in yield in exchange for the slightly higher probability that the borrower may default.
• Finally, investment-grade credit can provide an additional increase in yield compared to credit risk-free Treasury debt. In our view, many investors may fail to realize that the Agg could provide greater opportunities for return once they take a closer look at the individual components.
However, if investors simply allocated based on yield, the portfolio would be significantly over-weight credit and interest rate risk. In our view, this naïve approach to fixed income does little to enhance an investor’s prospects for return.
Through our approach to the Agg, when a variety of constraints focused on risk management are applied, the output of the Index methodology resulted in a portfolio with an additional 75 basis points (bps)
of income potential, while retaining a similar interest rate risk profile to that of the Barclays Agg.1
This incremental yield advantage is typically achieved through increased exposure to corporate and securitized debt and reduced exposure to U.S. Treasury securities. The implementation of relative sector and quality constraints, however, also helps the Index preserve the diversification potential of a broad-based, core fixed income strategy.
There’s an Exchange-Traded Fund for That
With the launch of the WisdomTree Barclays U.S. Aggregate Bond Enhanced Yield Fund (AGGY)
on July 9, 2015 WisdomTree packaged this unique approach in an exchange-traded fund (ETF). AGGY is listed on the New York Stock Exchange with a net expense ratio of just 12 bps.2
By searching for income within the investment-grade universe, AGGY could represent a step forward for investors looking to generate greater income potential while broadly retaining the risk characteristics of familiar core fixed income portfolios.

Important Risks Related to this Article
There are risks associated with investing, including possible loss of principal. Fixed income investments are subject to interest rate risk; their value will normally decline as interest rates rise. Fixed income investments are also subject to credit risk, the risk that the issuer of a bond will fail to pay interest and principal in a timely manner or that negative perceptions of the issuer’s ability to make such payments will cause the price of that bond to decline. Investing in mortgage- and asset-backed securities involves interest rate, credit, valuation, extension and liquidity risks and the risk that payments on the underlying assets are delayed, prepaid, subordinated or defaulted on. Due to the investment strategy of the Fund, it may make higher capital gain distributions than other ETFs. Please read the Fund’s prospectus for specific details regarding the Fund’s risk profile.
