BAMU vs VUSB

BAMUDBrookstone Ultra-Short Bond ETF

VUSBAVanguard Ultra-Short Bond ETF

In short

BAMU Most of the T-bill aisle just holds bills and charges next to nothing. BAMU goes the other way: an active manager steering maturities inside a 0 to 2 year band off its own read on the yield curve, for 1.00% a year.

VUSB Vanguard's first actively managed bond ETF, run by its in-house fixed income team and priced at 0.10%. It holds investment-grade paper maturing inside two years: a step past a money fund, well short of a real bond fund.

Stated mandate

BAMU The Fund seeks current income. It is actively managed and invests at least 80% of assets in U.S. Treasuries and investment-grade corporate bonds with maturities from 0 to 2 years, plus related fixed-income ETFs; it does not seek to replicate an index.

VUSB The fund seeks current income with limited price volatility while investing in diversified high- and medium-quality fixed-income securities. It expects to maintain a dollar-weighted average maturity of 0–2 years.

Why people hold it

• BAMU Does what the prospectus says: at least 80% in U.S. Treasuries and investment-grade corporates maturing inside two years. Portfolio and mandate line up closely.sec.gov
• The adviser dials duration to its near-term rate outlook and the shape of the yield curve, a lever the index bill funds in this category do not have.sec.gov
• Not just bills: an investment-grade corporate sleeve and fixed-income ETFs can add income potential beyond Treasuries alone. Income is paid quarterly.sec.gov

• VUSB At 0.10%, it costs half the typical ultra-short bond ETF and undercuts the other leaders in the group: SHV, PULS, FLDR and DUSB all charge 0.15%.
• Active, not adventurous. The managers buy investment-grade bonds (A3-or-better high quality plus BBB-tier medium quality) and hold average maturity to zero-to-two years.vanguard.com
• Income lands monthly, sourced from roughly 170 bonds, so no single issuer drives the outcome.
• A multi-billion-dollar fund that trades actively, and the same portfolio team also runs a similar Vanguard ultra-short fund.vanguard.com

Worth knowing

• BAMU The 1.00% fee is above the category median, and above ICSH at 0.08%, VUSB at 0.10% and VBIL at 0.06%. On a 0 to 2 year bond portfolio, fee eats a real slice of yield.
• Thinly traded next to the category's household names, so spreads can be wider and limit orders matter more.
• Credit and active risk ride along: corporates and ETF positions are not Treasuries, and the manager's curve calls can land either way.sec.gov

• VUSB This is not a money market fund. No fixed $1 share price, and the market price can trade above or below the value of the holdings.vanguard.com
• The mandate allows BBB-tier credit, a notch of risk a Treasury-only neighbor like SHV doesn't take.vanguard.com
• Bonds this short reprice with short-term rates, so the monthly payout drifts up and down instead of holding a set level.vanguard.com
