This is an actively managed bond ETF with no underlying index that pursues both total return and income across the investment-grade bond market. It uses Wellington's multi-strategy framework, which combines top-down rate and duration views with bottom-up security selection.

It suits investors who want stable interest income along with the opportunity to outperform the bond market.

It is an actively managed ETF launched in 2016 by Hartford Funds (managed by Wellington Management).

Wellington's dedicated bond management team builds the portfolio by weighing three axes together: interest rates, sectors, and duration. Generalist portfolio managers determine overall risk allocation, while sector specialists are responsible for selecting individual securities.

• Leverages Wellington's multi-manager structure
• Combines top-down rate views with bottom-up security selection

Assets under management (AUM) stand at $2.2B, and the expense ratio is 0.29% per year.

Within the same core bond category, passive ETFs such as IUSB and BNDX carry lower fees but offer limited scope to outperform the market. HTRB charges somewhat higher fees as an active management premium, but it can flexibly adjust positions when interest rates shift.

In an environment of frequent rate changes, returns on US investment-grade bonds have fluctuated considerably. Because of its active management, the ETF is drawing attention for its ability to adjust duration and respond defensively relative to the market in both rising and falling rate periods.

Steady inflows continue across US investment-grade bond ETFs overall. When rate uncertainty is high, interest tends to rise in active bond ETFs, which can adjust positions more flexibly than passive funds.

Wellington's professional management capability is a strength, but investors should also weigh the higher fees compared with passive funds and the risk of dependence on the managers.

The JCPB, BINC and PYLD shown in the table are competing ETFs in the same active bond category. They use multi-sector strategies from J.P. Morgan and PIMCO, respectively, and differ in fee levels and sector weightings. IUSB is a low-cost passive broad bond ETF and a direct substitute for investors who simply want core bond exposure. If the goal is passive core bond exposure, BND is an option, and for broad multi-sector exposure that includes high yield, BINC is also worth considering.

These are the key points to confirm before investing in HTRB. Because it is an active bond ETF, it is important to thoroughly review its fee level, interest rate sensitivity, and management approach in advance.

When interest rates rise, bond prices fall and short-term losses can occur, and because of the active approach, errors in the management team's judgment directly affect performance. With no currency hedge, fluctuations in the dollar-won exchange rate are also reflected in returns.

This is an active bond ETF worth considering for investors who trust Wellington's bond management capability and want a flexible response to changing rate conditions. If minimizing fees matters more, low-cost passive bond ETFs such as IUSB and BND are a better fit.
