LDSF vs SPAB

LDSFCFirst Trust Low Duration Strategic Focus ETF

SPABAState Street SPDR Portfolio Aggregate Bond ETF

In short

LDSF A one-ticket bond sleeve kept on a short leash: LDSF blends income ETFs, largely First Trust's own, to an effective duration of three years or less. Current income is the stated goal, capital preservation the backup.

SPAB A 2007-vintage core bond fund priced at 0.03%: roughly 8,500 US investment-grade bonds in one ticket, at the same rock-bottom fee the household names charge for the same index.

Stated mandate

LDSF The Fund seeks current income and secondarily preservation of capital. It normally invests at least 80% of net assets in U.S.-listed ETFs principally investing in income-generating securities with effective portfolio duration of three years or less.

SPAB The fund seeks to track the price and yield performance of the Bloomberg U.S. Aggregate Bond Index before fees and expenses, providing broad exposure to U.S.-dollar-denominated investment-grade bonds.

Why people hold it

• LDSF Mandate pins effective portfolio duration at three years or less, the documented lever for keeping rate-driven price swings smaller than a full-maturity bond fund's.sec.gov
• One ticket spans mortgages, investment grade corporates, high yield, senior loans and preferreds, with the prospectus capping high yield and senior loans at 40% of net assets.sec.govotcmarkets.com
• First Trust's team shifts the mix as its rate and credit read changes; the advisory fee is a thin slice, with most of the 0.87% total coming from the ETFs held inside.ftportfolios.com
• Income is the stated first objective and preservation of capital the second, and the fund pays monthly.

• SPAB 0.03% a year against a 0.36% median for its peer group, and the same ticket price as AGG, SCHZ and BBAG on the identical index.
• Roughly 8,500 dollar-denominated investment-grade bonds in one line item, tracking the Bloomberg U.S. Aggregate Bond Index. Diversification you could not assemble bond by bond.ssga.com
• Trades actively and has tracked its index closely, putting it among the stronger implementations in the core-bond group.
• Running since 2007, now a multi-billion-dollar fund, and it pays monthly rather than quarterly.

Worth knowing

• LDSF At 0.87% all in, it costs more than the typical fund in its category, and far more than core index trackers like AGG and BND at 0.03%.
• It trades thinly next to those giants, which can mean wider bid-ask spreads and more care on order size.
• Most of the ETFs inside are First Trust's own, a conflict the prospectus discloses, so you get one house's allocation call rather than a broad-market index.otcmarkets.com

• SPAB Bond prices move opposite yields. When rates rise the index falls and the fund follows it down; a 0.03% fee cannot cushion that.
• AGG, SCHZ and BBAG hold the same declared index at the same 0.03%. Picking among them comes down to spreads and platform, not the portfolio.
• Investment grade and US dollar only by mandate: high yield and foreign-currency debt sit outside the remit.ssga.com
