BAMU vs ICSH

BAMUDBrookstone Ultra-Short Bond ETF

ICSHAiShares Ultra Short Duration Bond Active 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.

ICSH BlackRock's active cash-parking sleeve, live since 2013: roughly 250 ultra-short investment-grade bonds and money market instruments, run for current income with preservation of capital, at 0.08% a year.

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.

ICSH The fund seeks current income consistent with preservation of capital through actively managed exposure to ultra-short-term investment-grade bonds and money market instruments.

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

• ICSH At 0.08% a year it undercuts the typical cash-alternative ETF, which charges about 0.20%, and comes in below top-rated rivals like FLUD and JPST.
• Actively managed rather than a fixed ladder: the team picks across ultra-short investment-grade bonds and money market instruments, spread over roughly 250 positions.ishares.com
• Trading since 2013 and now a multi-billion-dollar fund that changes hands actively, giving it one of the longer records in the cash-alternative aisle.
• Sits in the top quartile of its cash-alternative peer group, helped by high-quality holdings and low cost.

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

• ICSH Not a money market fund. The share price floats, and preservation of capital is the stated aim, not a promise.ishares.com
• It holds investment-grade corporate paper alongside money market instruments, so it carries credit risk a Treasury-bill-only fund does not.ishares.com
• It pays monthly, but the amount rides short-term rates, and as an active fund its results can drift from its 6-month T-bill reference index either way.
