Our read on each fund

ETF.net Research

CBOXCCalamos Tax-Aware Collateral ETF

VUSBAVanguard Ultra-Short Bond ETF

In short

CBOX No data

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

CBOX No data

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

CBOX No data

  • 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

CBOX No data

  • 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
