This is an actively managed bond ETF that invests most of its net assets in floating-rate senior secured loans (senior loans). It holds senior loans that banks and other financial institutions have extended to corporations, aiming for a high level of current income.

Its floating-rate exposure helps protect interest income when rates rise, making it suitable for investors who want high distribution income.

It is an ETF run by Virtus using an active management approach.

Under normal market conditions, the fund invests most of its net assets in first- and second-lien floating-rate senior secured loans to corporations. Because the coupons are floating-rate and linked to a benchmark lending rate, interest income adjusts along with rates when they rise, and the management team selects holdings through fundamental credit analysis.

• Coupon structure linked to floating rates
• Actively managed credit selection

Assets under management (AUM) are $305.0M, and the total expense ratio is 0.57% per year.

Compared with passive senior loan ETFs, active management adds credit selection, but fees are generally somewhat higher.

Because it holds floating-rate assets, the fund tends to react sensitively to changes in the interest rate environment. When rates are rising, coupons adjust upward, and its price stability tends to stand out relative to fixed-rate bonds.

When concerns about rising rates grow, demand for floating-rate assets tends to increase and money flows in. Conversely, when expectations of rate cuts strengthen, its relative appeal versus fixed-rate bonds may weaken.

Its strengths are resilience in rising-rate periods thanks to the floating-rate structure and high distribution income, while credit risk and liquidity are its weaknesses.

The investment-grade corporate bond ETFs shown in the table, such as LQD and USIG, and the high-yield corporate bond ETFs such as USHY, HYG, and SPHY are all centered on fixed-rate bonds, so their interest rate sensitivity differs from that of SEIX, which invests in floating-rate senior loans. Direct substitutes in the same senior loan and floating-rate category include BKLN, a leading passive senior loan ETF, and SRLN, an actively managed product. Investors who want investment-grade floating-rate exposure can also consider products such as FLOT.

Here are the points to review before investing in SEIX. Floating-rate senior loans offer resilience when rates rise, but it is important to also check in advance the credit rating mix of the borrowers and the liquidity conditions unique to the senior loan market.

Borrower credit deterioration and the low liquidity of the senior loan market are the main risk factors. In an economic slowdown, concerns about loan defaults may increase price volatility.

This is an active bond ETF suited to investors who want protection in rising-rate periods and high distribution income. If fees and liquidity are a concern, it is worth comparing it with the passive alternative BKLN, or with FLOT if you want investment-grade floating-rate exposure.
