Can one “core” total bond ETF replace the complexity of your bond holdings?

Recently “core” and “core-plus” actively managed total bond ETFs have become available.  A Wall Street Journal “Not All Total Bond Market ETFs Are the Same…” makes many interesting points about managed total bond ETFs, including the point that they have higher returns than index total bond ETFs. Owning only one total bond ETF that returns more than the index makes for an uncomplicated and appealing portfolio.  If you want the simplicity of owning only one bond ETF rather than actual bonds or multiple bond ETFs that yield more than the index, what should you consider?  Can you have low risk and high return with one bond ETF?

For example, Vanguard offers the Total Bond Market (BND), an index bond ETF containing only domestic bonds, average 8-year maturity with 69% government and 31% corporate investment-grade holdings. Vanguard also offers Core Bond ETF (VCRB).  It is an actively managed bond ETF and containing similar components as BND except for less government (48%) and more corporate investment-grade (52%) holdings. Not surprising, the total return of 7.08% for BND in 2025 is less than VCRB at 7.56%. The annual expense fee for BND is 0.03% vs. 0.10% for VCRB. Vanguard rates the risk/reward scale at 2 for both ETFs.

Many companies offer similar managed “core” and “core-plus” bond ETFs that represent the total bond market. They achieve higher returns than index total bond ETFs by increasing the risk with more corporate debt, high-yield debt, and selected foreign debt. They charge an annual fee in the range of 0.20% to .40% or more. Typically, management has discretion to vary the number of high-risk holdings over time so it takes some effort to find the details about their current holdings.

Currently I manage the risk and return of my bond holdings by owning a portfolio of index bond ETFs rather than one “core” ETF. My usual portfolio has domestic bonds weighed at 70% and international bonds at 30%.  For international bonds I use an index ETF holding only international bonds with an 8-year average maturity. Within the domestic holdings I use BND weighted at 50%, an index ETF with short term corporate investment-grade holdings at 25% and an index ETF with intermediate term corporate investment-grade holdings at 25%. In 2024 the one-year total return from my four ETFs was 2.93% vs. 2.11% for VCRB.  In 2025 the results were reversed with my four ETFs at 6.11% vs. VCRB at 7.56%. Note that the inception date for VCRB is 12-12-2023 so no more data points are available.

The simplicity of holding one total bond ETF with similar risk and return as my four ETFs is appealing.  However, the simplicity disappears if the holdings inside the one core ETF are hard to identify.  Do I need to monitor the current holdings of a managed bond ETF to be sure it has a reasonable balance of low-risk and high-return holdings?  Is monitoring one managed core bond ETF more or less work than re-balancing a portfolio of index bond ETFs to match the target percentages? Note that I would like to know where my assets are invested and that is easy to do with the four index ETFs. At the same time, I value the simplicity of owning just one bond ETF. I am interested in how others have addressed these questions.
