SOFRCAmplify Samsung SOFR ETF

VUSBAVanguard Ultra-Short Bond ETF

In short

SOFR The ticker is the mandate. Instead of owning a T-bill ladder and hoping it nets out to the overnight rate, this fund goes at the rate directly through Treasury-backed repurchase agreements, targeting SOFR after fees.

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

SOFR The Fund seeks current income matching the returns of the Secured Overnight Financing Rate (SOFR), after fund expenses. It aims to closely replicate SOFR and expects to do so principally through repurchase agreements.

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

SOFR Rare literal mandate: seek current income matching the Secured Overnight Financing Rate after expenses, principally through repurchase agreements. No duration bet, no credit-spread hunt.amplifyetfs.com
The portfolio matches the label. Repo against Treasury collateral, overnight in and overnight out, and it tracks the rate it names closely enough to rank in the upper half of cash-alternative funds.
Income lands monthly, and the 0.20% fee sits right at the median for cash-alternative ETFs.

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

SOFR Thinly traded next to the cash-parking giants, so limit orders and a look at the spread matter more here.
Payouts float with the overnight rate by design. When SOFR drops, what the fund passes through drops with it.
Median fee, not a bargain one: ICSH charges 0.08%, JPST 0.18%, and several peers land at 0.15%.

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
