XHLFABondBloxx Bloomberg Six Month Target Duration US Treasury ETF

In short

CMBO Most bond funds pick a duration and live with it. CMBO is actively run to roam across fixed-income sectors, maturities and credit quality using bond ETFs and rate derivatives, at a 0.15% fee.

XHLF Most cash-parking funds pick a maturity bucket. XHLF picks a number: it blends Treasury bills to an average duration of about six months, resets to that target monthly, and charges three basis points to do it.

Stated mandate

CMBO The Fund seeks total return through an actively managed strategy focused primarily on fixed-income ETFs and derivatives referencing fixed-income instruments or indices. Its exposure may span multiple fixed-income sectors, maturities, durations, and quality levels.

XHLF The Fund seeks to track the investment results of an index composed of U.S. Treasury securities.

Why people hold it

• CMBO 0.15% a year for an active mandate, well under the typical fee in its bond peer group.
• Duration is a dial, not a fixed setting: the manager can shift across sectors, maturities and quality tiers using fixed-income ETFs and rate derivatives.
• What it holds lines up closely with the fixed-income exposure its prospectus describes, so there is no drift between the pitch and the portfolio.

• XHLF Costs 0.03% a year, against a typical short-Treasury peer near 0.14%. In cash-like funds, where returns come from bills everyone owns, fee is the main lever.
• Tracks an index built to hold an average duration of roughly six months, rebalanced monthly, so exposure stays anchored instead of drifting as bills mature.bondbloxxetf.com
• Sits in the gap between 0-3 month bill funds and one-year funds. Its sibling XONE targets a one-year duration at the same 0.03%, so the two can be mixed to dial in duration.
• US Treasury bills only, no credit bets hiding in the portfolio, run in a multi-billion-dollar fund that has stayed close to its index.

Worth knowing

• CMBO A small fund that trades thinly. Spreads can be wide, so limit orders matter more here than in the giant core bond ETFs.
• Launched in November 2025, so there is no long record showing how the manager handles a full rate cycle.
• Index-tracking rivals like BND and SCHZ charge 0.03%. The extra fee here buys flexibility, and outcomes ride on the manager's rate and sector calls.

• XHLF Six months of duration is not zero. Prices move a touch more when yields shift than in 0-3 month bill funds such as BIL or CLIP.
• Income rides whatever Treasury bills happen to pay, and distributions arrive on an irregular rhythm rather than a fixed amount or schedule.
• Volume is moderate next to the largest bill ETFs, so spreads can be a bit wider, which matters more on big tickets than small ones.
