SIHY and SIFI: 2 Active Fixed Income ETFs to Consider

We believe that an increasing number of advisors are turning to active fixed income ETFs in 2023.

The Harbor Scientific Alpha High-Yield ETF (SIHY) and the Harbor Scientific Alpha Income ETF (SIFI) are active fixed income ETFs offering cost-aware solutions to gaining access to differentiated and scientifically driven fixed income exposure in the multi-sector and high-yield bond categories.

“With the Fed likely to pause their rate hiking program for a while, advisors are rethinking their fixed income allocations,” Todd Rosenbluth, head of research at VettaFi, said. “They might be willing to take on additional risk through high-yield to generate even higher than average income.”

SIHY and SIFI are actively managed by subadvisor BlueCove. BlueCove is a scientific asset management firm, founded with the specific goal of delivering strong investment outcomes for investors by researching, developing and implementing state-of-the-art scientific investment processes applicable to fixed income investment management.

Active scientific investing has the potential to offer investors a differentiated alternative to passive and traditional active discretionary strategies by benefiting from the significant breadth and applying insights that otherwise maybe difficult to capture, according to Harbor Capital Advisors.

As of May 4, 2023, SIHY and SIFI have a subsidized SEC yield of 8.01% and 6.79%, respectively, according to Harbor’s website, and SIHY has accreted $125 million in assets and SIFI has $32 million in assets under management. Both funds were launched in September 2021.

SIHY seeks to provide total returns through employing a structured investment process that utilizes a proprietary model-based framework in the security selection of high-yield bonds.

SIFI also employs a structured investment process and utilizes a proprietary framework the asset allocation and security selection of both investment-grade and below investment-grade (high-yield) bonds. As of March 31, 2023, over 60% of the portfolio was in high-yield bonds and over 35% of the portfolio was in investment grade corporate bonds.

SIHY was the focus of a milestone development for the industry earlier this year. The Harbor High-Yield Bond Fund (HYFAX), a mutual fund, was merged into SIHY in February 2023, adding $117 million to the ETF while allowing investors in the mutual fund to benefit from the liquidity and tax advantages of the ETF structure.

SIHY and SIFI Risks: Fixed income securities fluctuate in price in response to various factors, including changes in interest rates, changes in market conditions and issuer-specific events, and the value of your investment in the Fund may go down. As interest rates rise, the values of fixed income securities held by the Fund are likely to decrease and reduce the value of the Fund’s portfolio. There is a greater risk that the Funds will lose money because they invest in below-investment grade fixed income securities and unrated securities of similar credit quality (commonly referred to as “high-yield securities” or “junk bonds”). These securities are considered speculative because they have a higher risk of issuer default, are subject to greater price volatility and may be illiquid. Because the Funds may invest in securities of foreign issuers, an investment in the Funds is subject to special risks in addition to those of U.S. securities. These risks include heightened political and economic risks, greater volatility, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, possible sanctions by government bodies of other countries and less stringent investor protection and disclosure standards of foreign markets.

Model Risk: The strategies and techniques employed in a quantitative model cannot fully match the complexity of the financial markets and therefore sudden unanticipated changes in underlying market conditions can significantly impact their performance. The effectiveness of the given strategy or technique may deteriorate in an unpredictable fashion for any number of reasons including, but not limited to, an increase in the amount of assets managed or the use of similar strategies or techniques by other market participants and/or market dynamic shifts over time.

Unlike mutual funds, ETFs may trade at a premium or discount to their net asset value. The ETF is new and has limited operating history to judge.
