SCHZ vs WSDB

SCHZASchwab U.S. Aggregate Bond ETF

WSDBDWeitz Short Duration Bond ETF

In short

SCHZ Schwab's core bond holding: the broad U.S. investment-grade bond market, over 10,000 issues deep, for 0.03% a year. That is the floor of a category whose median fee is more than ten times higher. Running since 2011, pays monthly.

WSDB Weitz has run this short-duration credit playbook from Omaha since 1988. WSDB is the ETF version: active bond picking across credit qualities, with a duration target of one to three and a half years.

Stated mandate

SCHZ The fund seeks to track the total return of an index representing the broad U.S. investment-grade bond market.

WSDB The Fund seeks current income while preserving capital.

Why people hold it

• SCHZ 0.03% a year sits at the category floor, against a cohort median of 0.36%. Only a short list of aggregate-bond funds matches it, including AGG, BND and SPAB.
• Tracks the Bloomberg US Aggregate Bond Index tightly, one of the cleanest index implementations among the 187 funds in its peer group.schwabassetmanagement.com
• One ticker, thousands of investment-grade U.S. bonds, income paid monthly. The plumbing of a bond portfolio without buying a single bond yourself.
• Live since 2011 and now a multi-billion-dollar fund that trades actively, so trading costs on ordinary retail-sized orders tend to be minor.

• WSDB The ticker is new, the strategy isn't. Weitz has run this short-duration approach since 1988, when it started as a mutual fund, backed by a multi-billion-dollar bond platform.businesswire.com
• Duration stays short by design: a target average effective duration of one to three and a half years, muting price swings from rate moves versus intermediate and long bond funds.stockanalysis.combusinesswire.com
• Actively managed across the credit spectrum, from Treasuries and agency mortgages to corporate and securitized paper, aiming for current income while preserving capital.sec.gov

Worth knowing

• SCHZ This is duration exposure, not a cash substitute. Interest-rate moves, not credit selection, drive most of the ride, and that is the weakest part of its risk profile.
• Investment grade and U.S. only: no high-yield, no foreign bonds. Funds like BNDX cover the international side of the cohort.
• The aggregate-bond aisle is commoditized. Against AGG, BND and SPAB at the same 0.03%, the differences come down to index variant and where you already custody, not fee.

• WSDB Costs 0.45% a year, above the typical bond fund in its cohort and far above index giants like BND, SPAB and SCHZ at 0.03%. Active credit work is the thing you're paying for.
• A 2026 launch with a small asset base and light trading, so bid-ask spreads can matter more than the expense ratio on a single trade.
• Short duration trims interest-rate risk, not credit risk: reaching into lower-rated corporate and securitized debt brings downgrade and default exposure.stockanalysis.comsec.gov
